Is there any information on what video features the 8500GT supports, and which ones it doesn't, beyond the H264 offload? I am mainly looking for features the 8500GT can't handle, while the 8600GT can (Trying to decide which one to get for a non-gaming HTPC)

Does it support spatial temporal de-interlacing, inverse telecine, bad edit correction, etc...?
I know the 7600GS didn't support inverse telecine, and the 8500GT is supposed to be replacing the 7600GS.

Hi guys-

With the 8600GT, can anyone think of a reason a E6600 wouldn't be fast enough for even the most challenging HD-DVD or Blu-ray disc?

Thanks,
Chris

I don't know how to verify all these, but deinterlacing of HD material looks flawless to me now, I had many issues with 7950 GT. Also, motion on both cinema and video material looks silky smooth.

With these cards I think that even a non-overclocked E4300 would be enough for the "toughest" BD/HD DVDs

nope. the whole point of 8500/8600 is you don't NEED an E6600 for BR and HDDVD. Heck with an E6600 you'll be fine with any recent card.

But I'm waiting too see ATI's UVD, which promises to offload both VC1 and H264. ATI has also had a better track record on viideo processing than nvidia.

Great - thanks.

I'm just hoping that ATI card can output 7.1 LPCM... that would be huge.

I was wondering the same thing. Only documentation I can find:

http://www.nvidia.com/object/geforce_8600_8500_tech_specs.html

Seems to suggest so, but NVidia's "feature" sheets in the past have frequently been woefully inaccurate.

Using the 8500GT, it certainly does IVTC on MPEG2 1080i, and seems to do bad edit correction as well. Spatial-temporal I don't know, because we use h264 for broadcast HD in Britain.

For h264/vc1, previously only the 8800 could do ivtc/badedit/s-t. The 8500GT appears to be doing spatial-temporal on BBC HD (20mbit 1080i50), but it's hard to compare as so many decoders are a bit wonky with MBAFF interlaced content. I can't test the other two as IVTC isn't needed on 25/50hz AVC material, and bad edit really isn't much either.

interestingly enough, the spec sheet indicates vc-1 and mpeg-2 acceleration, but the testing we've seen shows minimal benefit for vc-1. perhaps that a driver thing or a bios update.

Got the Gigabyte 8600 GTS fanless card today. Installed it to my AMD 64x2 3800+ (overclock to 2.4GHz) with 64-bit version of windows vista, with 158.24 beta nvidia driver, connect to a HDCP compliant projector. Running CyberLink Advisor shows DVI output with no HDCP :-( I can't play HD-DVD movie directly from the external HD-DVD player. I can play ripped movie from hard disk fine. However, no matter I select hardware acceleration or not, the cpu usage is about the same (40 - 45%). Need to play it more to figure out how to turn on HDCP and hardware accleration.


You're the third 8600 GTS user on this forum to not have any hardware accelerated H.264 decoding in Windows Vista 32 bit with the latest PowerDVD 7.3.

[EDIT] Oops! You have the 64 bit version of Vista. PureVideo HD of the G84 variety only works on Vista 32 bit.

Could you clarify why PureVideo HD of the G84 variety only works on Vista 32 bit? According to nVidia web side, 64 bit vista driver does have PureVideo HD support:

This is from nVidia's release notes for 158.24 beta for Vista.

How does one control inverse telecine and other settings, anyway? I suppose if i could find how to disable/enable that, it would tell me if my VC-1 decoding is being accelerated.

GeForce*8500/8400/8300:*Playing*VC-1*titles*in*full-screen*mode*results*in*green*flashes.**[302116]

That's interesting. I don't get those but I don't seem to be getting GPU-accelerated VC-1 playback, either.

Since my overclocked Pentium M 760 (2000MHz@2250MHz) plays VC-1 HD-DVD at approx 95% CPU in PowerDVD, I am going to try a Pentium M 770, which will yield 2.13@2.4GHz overclocked.

It's in the control panel somewhere, under the video/tv settings, rightmost tab. It's enabled by default in recent drivers, which is fairly idiotic when a) it's buggy, and b) the decoder does IVTC anyway.

Any chance you'd be willing to try sticking something in there, just to see? For instance, does it touch, does it not even fit at all, etc. I had high hopes for this card replacing the onboard video for me, and if this indeed doesn't fit, I've yet to see a similar version that seems like it would fit better and still handle dhcp for a similar price...

I tried putting my sound card in next to it. It'll fit, but they touch and it's a bit tight. I'm not real comfortable with a card up against the heatsink like that, but maybe it's no big deal.

I just tried out the Gigabyte 8500GT it is better than my 8800GTS in every respect.

I could never get H.264 hardware acceleration to play without frame drops with the 8800 and it works perfectly on the 8500. I am not a gamer so I will be selling the 8800.

CPU with VC1 and MPEG2 are both the same: <50% and <30%.
CPU with H.264 went from >80% to about 45%.

System power (watts):

8800 Idle: 170
8800 Load: 235
8500 Idle: 101
8500 Load: 135

Obviously, my system is running cooler so it makes less noise now.
This is a fantastic card!!

Thanks for doing that.

Any thoughts from the masses about the wisdom of an install like that? It certainly doesn't sound like something that'd be a good idea, but maybe others have had similar situations and it's proven to not be a problem?

You don't. HW accel is only supported with Vista and HD-Purevideo compatible players (PowerDVD 7.3+patch being one right now). Media player/Quicktime/etc. will not see any benefit.

It's been mentioned in the thread multiple times.

Hi there

If the vid card is in the vertical plane (ala HTPC case) and there are ventilation holes above it, then you just might get away with this. The convection cooling is still far from optimal since the only source of air is from the base between the MB connectors. BTW the Gigabyte heatsink seems designed for this since it has vertical heatsink fins, compared to the horizontal fins of the Asus 8500GT card.

If the card is in the horizontal position (tower case), then you'd likely end up cooking the electronics, since the heatsink is on the bottom side sandwiched between 2 circuit boards. But the Gigabyte does have an interesting extension of the heatsink (with slots no less!) beyond the end of the PCB so there is some dissipation in this position.

More correctly, hardware acceleration is supported with Vista and a PureVideo compatible codec. PowerDVD's H264 codec is one of these and works with acceleration in any DirectShow player (as long as a compatible renderer is used)

Not much to the 8600GTS. The noise is up from the 8800GTS, but power usage is about 100watts less at load.

For gaming, it about the same as the 7600GT. Check out this Guru3D article (http://www.guru3d.com/article/Videocards/426/1/).

I have noticed some stair-stepping when hardware acceleration is enabled in PowerDVD 7.3 and BD/HD titles.

I tried a number of settings changes in PowerDVD and I could not get them to go away. Finally, I set the Hardware Acceleration on, Quality to Auto in PowerDVD and used the NVidia control panel to set the the 3D quality to Best (from Application Controlled). That did it.

What a great card!

However, I feel its picture quality is not as good as when using it in xp. Since my cpu load is ok and GPU offload is not important at this moment, I switch to xp (with nvidia 158.22 driver). I upgrade from Geforce 6600. The PQ is a big improvement.

Folks,
I am having an issue with this H78DC3 and a HTPC running Vista 32 bit with the new nVidia 8600 GTS card.

1. When I feed the PJ 1280 x 768 the PJ thinks that it is being fed 1024 x 768. (upon re-sync, it displays this rez) If the PJ’s selected aspect ratio is “Native” I get a 4:3 window in the middle of the screen; instead of getting a wide-screen image. The image is also not clear, text is barely readable.

2. Before I upgraded I just had the on-board Video and it was working absolutely fine at 1280 x 720 and PJ at native.

3. I am not able to select 1280 x 720 as a resolution. It is simply not available. The closest is 1280 x 768.

4. The PJ does detect 1280 x 960 correctly but the image is still not clear, text is barely readable.

Please help !


PS: there is nothing wrong with the HTPC because I tested it by connecting it to :
1. a CRT monitor
2. Another projector.
3. By the way, the HD-DVD playback is the smooooooooothest I have ever seen. And that too on 60Hz.

My PJ is 1280 x 720 native. I believe when I move my PC from LCD monitor (1280 x 1024) to PJ, my PC automatically detects the correct resolution over DVI (didn't try VGA). I didn't do anything for this. Try "List All Modes..." under Adapter tab in advance settings to see if that helps.

OK, I maybe wrongly assumed that you use Vista. Under Vista you cannot use any custom resolutions yet, so Powerstrip can't help. Things may be different with XP, though.
This is definitely a driver issue - the driver does not recognize the reported paramters by the monitor. How it works for some people and not for you is pure luck until Nvidia fixes it. Only 2 of their 8 Vista driver releases so far correctly recognize my DLP TV's resolutions when connected over VGA.

Had my eye on an 85/8600 since I had hoped to build a myth system that would also serve for development and a few Oracle instances - wanted to save all the CPU cycles I can..

Is it reasonable to expect that Linux driver support will be forthcoming, or should I assume the worst and budget for a faster CPU ?

I don't know about the latest Intel integrated video chip, but past ones work well with Linux. NVidia is a close second followed by ATI. You can never go wrong with a fast C2D CPU. Buy a C2D E6600 in case software rendering is in your future.

I was reading this thread with interest as I'm currently looking for a way out of my 7900GS based colour banding / posterization hell - which has been present when using most video playback (regardless of CODEC).

Is there anyone who has upgraded from a 7x00 series GPU to an 85/600 series here who can confirm that the posterization issues are now resolved? It was particularly bad when using applications such as PowerDVD to view HD-DVDs. An example would be extreme colour stepping on for example the HD-DVD promo video , or on Warner discs - the yellow and blue Warner Bros. logo.

Can anyone test whether this posterization is still present on the new cards, if it isn't I will upgrade immediately as it ruins my machine's use as a HTPC to feed a projector.

Many thanks in advance.

Well, I have not used the 73oo so I have no reference, but I can tell you one thing for sure.....

This 8600 GTS I bought performs flawlessly! :D :D

Absolutely smooooooth image, no judder while panning even at low refresh rates of 60Hz (useful for my CRT PJ with low bandwidth)

No color imbalance issues. No atrifacts etc etc.

I am runnning it on Vista 32 bit with Core 2 Duo 6600 on a Intel D965WH motherboard.

HD-DVD player is the x-box 360 add-on drive.

Power DVD 7.3 ultra.

I use the VGA output to my CRT projector. Have not used the DVI o/p yet. I have also tested it with an Optoma H78DC3 with same results. (VGA signal again)

I have compared my HTPC's HD-DVD playback with the Toshiba A-1, it beats the Toshiba panties down ! ;)

I was reading this thread with interest as I'm currently looking for a way out of my 7900GS based colour banding / posterization hell - which has been present when using most video playback (regardless of CODEC).

Is there anyone who has upgraded from a 7x00 series GPU to an 85/600 series here who can confirm that the posterization issues are now resolved? It was particularly bad when using applications such as PowerDVD to view HD-DVDs. An example would be extreme colour stepping on for example the HD-DVD promo video , or on Warner discs - the yellow and blue Warner Bros. logo.

Had my eye on an 85/8600 since I had hoped to build a myth system that would also serve for development and a few Oracle instances - wanted to save all the CPU cycles I can..

Is it reasonable to expect that Linux driver support will be forthcoming, or should I assume the worst and budget for a faster CPU ?

Your best bet is to just to get a motherboard with Intel integrated graphics if your CPU will be sufficent and you will not be doing 3D work. The drivers are fully open source and support Xv. Your only advantage from getting a nVidia GPU is enhanced 3D rendering and XvMC support. XvMC only accelerates MPEG2 and isn't really needed with a reasonably speedy CPU. Plus, it limits your deinterlacing options.

I do not think that nVidia will provide any additional video playback acceleration anytime soon.

Anybody know anything about this card, or when it might be avaiable?

PNY Verto GeForce 8500GT - VCG85512GXPB (http://www.amazon.com/PNY-GeForce-8500GT-VCG85512GXPB-Express/dp/B000P9CWTI)

Looks like it's another 8500gt (512mb) with HDCP (in addition to the Gigabyte one) and although this one isn't fanless, it also might fit better into a PCI - PCI - x16 - x1 configuration like mine without having to worry about that huge heatsync melting the PCI card.

What do you think? Better to have the Gigabyte heatsync basically touching the back of the PCI tuner card, or the PNY fan spinning?

Keeping in mind that this is a living room htpc case system.

Thank you ! At the risk of going further OT (sorry), would integrated graphics be enough to display 1080p ? I thought I had read it would not be enough, which was why I was looking at the 8500/8600. If it is enough, can someone recommend a motherboard with DVI out that overclocks well ? I was looking at the Gigabyte 965G-DS3 which apparently OCs well, but only provides VGA out.

Intel G965 graphics can do 1080p. Hardware acceleration is limited to MPEG-2 and VC1-- and I'm not certain that the Intel Linux guys have implemented HW accel in the drivers at all, yet.

But you should be able to get 1080p out of any Core 2 Duo, and possibly out of some of the Pentium Ds as well. Blu-ray-level high-bitrate H.264 may be a struggle for E6400 and below, but the rest should be fine.

Yes, an Intel 915G/GMA 900 is sufficent to output 1080p, and that's two generations old compared to the latest GMA 3000-series GPUs.

there isn't any acceleration in nVidia GPUs for Linux besides Xv and XvMC. XvMC is only usable for MPEG2. (and any of the CPUs you'll consider will probably play MPEG2 anyway)

Xv is available for Intel GPUs and as well (think Windows's video renderers)

I have an nVidia 8500, Vista Media Center PC, latest Power DVD, BluRay drive. Nothing else installed on the system. Pretty simple setup. AMD dual core CPU.

While watching a BluRay video, at random points, the playback just stops. No sound. No video. It's as if I pressed Pause or something. Interestingly enough, the timer continues to increment. PowerDVD is still reading the BluRay drive, incrementing the timer, just not sending out any audio/video. Pressing Pause/Play doesn't unstick it. I have to press Stop, and then Play to get it to continue again.

It seems like a PowerDVD bug to me. It could also be a driver bug somewhere too though I have made sure I have all the latest video drivers, sound drivers, Vista updates, etc.

Has anyone here seen this before? Thanks!

I'm not sure about intel's onboard video solution can do 1080p.

I have a D965WH, and it had a hard time playing SD DVDs smoothly. Surely it would play them but there would be lot of motion judder.

I think it may output 1080p but would be be usable for playing HD content? I seriously doubt that.


BTW, after I got the 8600 GTS, everything is smooooth.

I think I have seen a similar problem once or twice.

Here is what happens:
I try to start playing a HD-DVD by hitting the play button on powerDVD. The HD-DVD starts playing for just a second or two and then the usual red powerDVD's default screen comes up.

I hit the play again and nothing happens.
Then I have to quit power DVD and then re-start power DVD. Then it works.

It is not frequent.

I think there are some updates out on powerDVD's site which may fix this issue.

It will output 1080p but the CPU will have to do all the work. So if you are doing h.264 you'd need an e6600 or better.

BTW... I've got the same board and it easily handles 1080i/720p mpeg2 playback with an e6300. There were some drivers that gave me jumpy playback. Once I got some decent drivers it's been smooth as silk.

HI
I was looking for the same solution and I think I've found it:
MSI NX8600GTS-T2D256EZ-HD
http://global.msi.com.tw/index.php?func=proddesc&prod_no=1197&maincat_no=130
+
ASUS P5B Delux or Delux/WiFi or Premium
http://www.asus.com.tw/products.aspx?l1=3&l2=11&l3=307

The video card fits perfectly with it's topside heatsink. Both the videocard and the mobo are fanless which is very nice. There is only one thing you should be careful with - the height of the RAM modules (for example the Dominators from Corsair are very tall and hit the VC heatsink). ... well with a litle bending of the heatpipes of the VC one could even solve this problem ;)

Sorry for my ignorance on these topics, but I am new to the HTPC scene and wanting to build a system.

I was wondering if this card will help with playing 720p/1080p mkv files. My Vista Ultimate setup plays back 720p files fine but 1080p files just stutters like crazy. I am currently using ffdshow as codec. Do I need additionally software for the hardware acceleration with this card? Or can I playback the 1080p MKV files Vista Media Center? I don't want to spend additional money on playback software if I don't have to. Thanks for any help.

At present, 8500/8600 h264 hardware acceleration outside the PDVD app only works if you have all of these:

1) Vista
2) very recent drivers (158.xx or higher?)
3) a compatible decoder - only one I know is PDVD 7.3.
4) a video playback app that uses the Enhanced Video Renderer: WMP11, Theatertek 2.5, recent MPC betas. Probably most video playback apps will add this soon enough, it does have some nice benefits.



FFDshow will likely never work with hardware acceleration. CoreAVC.... maybe. WInDVD beta can accelerate h264 discs, so its codecs may work also. Next's month's drivers will open things up to XP, and presumably lift the EVR restriction also.

I connected my new HTPC setup to my 73" Mit (WD-73732) tv last night. I am using the DVI input on the tv, with DVI set to digital on the tv. The problem is that the bottom, top, left, and right most of the HTPC display is not displayed on the tv. For example, I can not see the start bar at the bottom of the page nor can I see the top bar at the top of the full page window. And the left and right edges are cut off.

My setup
EVGA 680i w/ E6700, 2GB
EVGA 8600GTS gpu - current driver available from the evga website
Vista Ultimate 32bit
PowerDVD Ultra 7.3

I set the display resolution on the 8600GTS to ...x1080 using the Nvidia Control Panel. The tv displays it is in 1080p mode when I hit the info button. I watched a few 1080p sample files and the picture looks great. Just can not close PowerDVD or any other full screen windows or turn off the computer using the start button since I can not see it.

Any ideas?

It's not the latest "official" beta drivers from Nvidia.com, it's some leaked drivers that were mentioned here in another topic - 160.xx - that have the overscan correction. I tried them last night and they really have it, but they are the buggiest drivers I've seen - for the first time I wasn't able to get 1:1 pixel mapping through DVI even using my native resolution. I got 1:1 only for a split second before entering the Overscan adjustment screen. Looks like somebody went and hacked through the code just to enable the overscan functionality, while screwing up everything else.

Tried to back down to the 1772 resolution for the 8% underscanning, and the size didnt change at all. I am using component output. Also tried the latest beta on nzone, and same thing.

Well to be honest, I dont know if an "i" shows on the screen or not. Running 1920x1080i @ 30hz over component on an older RPTV doesnt really lend itself to reading text. I would assume its a function of my connection method, as opposed to going over DVI/HDMI?

I didnt have a chance last night to try the 160.0x drivers from guru3d. Maybe this weekend I can give it a go. What I really need to do is get VNC workong on my Vista HTPC so that I can connect in without blacking out the main display like RDC does. Then I will be able to mess with display adjustments and actually read what is displayed on the screens via my laptop screen.

Yeah, thats Remote Desktop Connection :) RDC. VNC allows you a bit more flexibility in some things, you can even shutdown/reboot the remote system, which I have never seen that option in RDC. Maybe I just missed it. Plus with Vista at least, when I RDC into my HTPC (coming from an XP laptop) I can not gain direct access to the video card resolution settings and attributes. With VNC you can.

rajdude
05-11-07, 08:55 AM
Nope!

RDC is slightly different (although they do use the same protocol).
Look into XP's system properties >>> remote tab.

There are two different checkboxes.

here is the "about" blurb:



About Remote Assistance
Sometimes the best way to fix a problem is to have someone show you how. Remote Assistance is a convenient way for a friend in another location to connect to your computer from another computer running a compatible operating system, such as Microsoft Windows XP, and walk you through your solution.


After your friend is connected, he or she will be able to view your computer screen and chat online with you in real time about what you both see. With your permission, your friend can even use his or her mouse and keyboard to work with you on your computer.


Notes

Both you and your assistant must be using either Windows Messenger or a MAPI-compliant e-mail account such as Microsoft Outlook or Outlook Express.
You and your assistant need to be connected to the Internet while using Remote Assistance.
If Windows Firewall is turned on, Remote Assistance will temporarily open firewall ports.
If you are working on a corporate or local area network, firewalls might stop you from using Remote Assistance. In this case, check with your network administrator before using Remote Assistance.



Note that the procedure to connect to remote assistance is different than RDP. It goes via messenger. I do understand that VNC may be more straightforward (does to this quirk)



And, to shut down/reboot a system via RDP, right click on the taskbar and click on task manager. There is a shutdown tab there . That has multiple options!

The problem is when I try to play HD DVD using PDVD ULTRA, the picture blinks in and out. At 720p the problem does not occure.

You need to use an app with VMR9 as the renderer - at present PDVD's mpeg2 codec doesn't support dxva2, so doesn't accelerate anything with the 8500 in PDVD itself (which appears to use EVR).

Try Media Player Classic, since it's free.

This is the first time I hear that memory bandwidth has any influence on video playback. Not that it may not be true, but I've never seen or witnessed a proof of that, or even the very idea brought up. And certainly don't think that 8600 can do anything that the 8500 can't as far as video is concerned.

It doesnt work with SD DVD at 1080i either, using VMR9 with zoomplayer. FFDShow and Nvidia Purevideo decoder. Also the XFX 8500GT card is not HDCP. But using PDVD it plays HD DVD fine at 720p and with Zoom+FFDshow+Nvidia with SD DVD at 720p. Just doent do 1080i for vid playback.

Have you tried with Cyberlink decoder in ZP? Nvidia's decoder is basically obselete, they've given up develoing it so no surprise when it doesn't work with newer cards.
Funny that it works in 720 but not 1080. Returning the card and getting a 8600GTS with HDCP. You get what you pay for I guess... :rolleyes:

I dn't know why you guys continue to bang your heads over the most difficult and almost impossible problem - to get an HTPC to output flawless interlaced resolution. Even if you set the desktop to be 1080i, AFAIK no player can pass exactly the 1080i material without down -p and so on scaling and interlacing, effectively killing a huge amount of the resolution.

I get my stuff local or from NCIX.

Silent vid cards are great on paper, but after using a few I found them not the ideal for "my" HTPC builds. Yes they are silent but you really need good air flow to make them effective. In most HTPC cases, the air flow is limited due to case design/size and the desire to keep intake/exhaust fans quite has limited what a passive cooled vid card can do in my builds. Every one I used in the past always heated the inside of the HTPC up and needed more air flow from various fans and the noise was just trade off between the case fans and the passive vs active vid cards. Yes they work but usaully the passive versions cost more then the active ones. Its just comes down to a trade off, a little noise from the vid card or a little noise from the case fans. Just IMO :)

You're quite right - it's really common problem (and not just in HTPC cases). The way I got around it was buying a 120mm fan and rubber mounting it on top of the (previously fanless) heatsink. You can then downspeed said fan to 700/800rpm or so, at which point it's basically silent. It's still kicking out far more air then the typical useless 60mm GPU fan running at hurricane-noise speeds, so cooling is no problem either.

An even smarter way would be a case where a 120mm gpu fan blew air over the heatsink and exhausted it directly out the back, and also acted as the case's main fan exhaust. Something for the custom builder I think :-)

Anyway, I don't know why gpu makers haven't started using larger fans - for HTPC noise purposes you'll never get a 60mm to work properly, or even a 80mm. A good 92mm might work though - 120mm is ideal, but isn't the easiest to shoehorn into tight spaces.

Yes. I have one, they can be found cheaper than that. Pricegrabber is your friend.
Before that I had an 8800GTS. Without Hardware acceleration, it performs the same as the 8800. With hardware acceleration it is about 70% less CPU on HD mpeg4.

Also, uses 70 to 100watts less power in my HTPC.

Not as clean with the DVI-HDMI route compared to the straight HDMI of the MSI card but its plus's are DX10, dual linked DVI's and maybe future HD GPU accelleration in XP.

just to amplify Arfster's comments..

I have the Gigabyte 8600GTS which is fanless. Yes, it works well, the GPU temperatures are quite reasonable. However, the heatsink puts out a massive amount of heat. The heat sink faces away from the CPU, and away from the exhaust fans in the case (rackmount). In order to get the heat out of the case, I'm going to waterjet a blowhole above the area where the vid card and the expansion cards go, and mount a Nexus 120 mm fan controlled with a zalman fanmate (hopefully will be inaudible). While I'm at it, I'm going to mod a hard drive enclosure that has 3 heinously loud fans, and the top of my rack enclosure to vent out heat from the receiver the same way.

I can't comment on VC1 with these drivers, but overall I do seem to be getting worse performance with them on a XP SP2 box (w/ 8600GT). It's acting like it isn't doing anything.

Using the Windows KMPlayer (not related to the KDE Linux flavor) and switching between it's internal H264 and Cyberlinks saw no difference in CPU usage. DXVA is checked and verified KMPlayer's internal was off.

Prior I was getting about 30-35% on an AMD2 3800, but now getting 45-67% with spikes up to 100% with the same source. I tried various overlay modes as well.

It's the same (albeit much lower CPU usage) with DVD content in PowerDVD.
Either with Hardware Enabled or not, the CPU usage is the same.

And yea, I could be doing something wrong here and will reload with the "old" drivers to verify.

Only issue I(I think) is the airflow over the heatsink. Using Ntune utility, monitored the CPU at 31C but the GPU is running 65C when watching HD DVD content.

Would like to find out other's GPU temps are similar and should I worry about finding additional airflow.

Thanks Arfster and Crispy for the feedback on temps. I won't worry now and I'll just leave the case as is. Very nice to have a quiet system- this one is in the master br so silence is a big factor.

Joseph- I am running XP MCE, so no acceleration for HD DVD. Using AMD Athlon XP dual core 4600 (legacy 939 socket stuff) on an Asus 6150 type MB (don't use the onboard graphics). Looking at CPU utilization it was somewhere around 50-75%. System is about a year old so probably would do things a lot differently now.

I have primarily been watching HD, so my observations are probably limited. However, even the standard XP desktop looks clener. I am using it via VGA output (over DVI connector) into a 1920x1080 Sceptre display. I'll have to look closer at SD DVD (but once you get spoiled by HD.....)

The GPU in the 8500/8600 cards ONLY accelerates H.264. This has been covered by Anandtech.com (http://www.anandtech.com/video/showdoc.aspx?i=2977&p=1), hardspell.com and a summary of the hardspell article (Chinese website) can be found here http://www.avsforum.com/avs-vb/showthread.php?p=10357876&&#post10357876.

VC1 content is only partly accelerated in nvidia 8x00/7x00 gpus. So it isn't surprising that under XP it doesn't seem to be any better.

Yeah, a few people have this. In PDVD while playing h264, goto config/info - is dxva on?

Also, try this setup in graphedit: filesource (some h264 evo) > haali splitter > cyberlink decoder (acceleration on in properties) > Enhanced Video Renderer.

Reason I suggest this is I suspect PDVD mis-picks renderers at times. For the 8600 to hardware accelerate, it needs to be using EVR (at least with current drivers).

Yes, Slysoft has been around a while. I have used their stuff for years and never had a problem; they update constantly. And unless Antigua and Barbuda stops them there is little a US company/group can do about their software. The parties that try to prevent copying will try to build a better safe but it will only result in the evolution of better safecrackers. In my eyes stuff like HDCP is like shutting down the freeways to prevent cross-border smuggling/trafficking (or only allowing BMWs on them).

As soon as I get my 8500 card (if it isn't already HDCP ready) I will get AnyDVD-HD. Then I can play HD-DVDs on my HLS4676S. I have AnyDVD and have used it for years. I got it originally to play DVDs from Asia or Europe (all legal ones if you were wondering ;)) on my computer.

Actually it's worse than that. VC-1 isn't accelerated at all under Windows XP on the G84 at the moment (There're no VC-1 capability bits reported by DXDiag, only MPEG2 modes A, B, C and D ).

Someone was saying that there's no MPEG-2 acceleration in Vista. That's blatantly not true. I've tested it and certain types of MPEG clips (both SD and HD) are accelerated by PowerDVD Ultra under Vista 32 bit ( The capability bits reported under Vista are MPEG2 modes A and C, which is worse than under XP).

Still waiting for the XP drivers for hardware acceleration on my 7950. It's still grayed out in PowerDVD.


I don't know about the 7950 about Purevideo HD has been enabled for the GF 7 series for a long time now.

anybody who has the gigabyte 8500gt have a dell e520 by any chance. Im looking at getting this card but am not 100% sure if it will fit ok. Its hard to find any good pictures of it, but the heatsink seems to come out a bit at the end which might a bit too much for this pc. Currently have just ati x1300 in it. The asus passive 8500gt seems like the only risk free option but then theres no hdcp if its ever needed.

Someone was saying that there's no MPEG-2 acceleration in Vista. That's blatantly not true. I've tested it and certain types of MPEG clips (both SD and HD) are accelerated by PowerDVD Ultra under Vista 32 bit ( The capability bits reported under Vista are MPEG2 modes A and C, which is worse than under XP).

It's not that it doesn't accelerate MPEG2 as such - it's just that all current decoders can't do DXVA2 (excepting the crappy MS one), and as a consequence there's no acceleration when the playback is using EVR. You can demonstrate this in graphedit quite easily. Also by running WMP11, which uses EVR by default. It's a shame not to be able to use EVR generally, because it has many improvements over VMR9 (particularly related to tearing).

On top of that, PDVD has some oddities with renderer choice. In HDDVD/BD mode, it appears to choose EVR or VMR9 as appropriate to ensure acceleration (either that or it's using custom hooks for _everything_). DVD mode uses VMR9, so you're OK. However, file mode is EVR, so you get....

I'm so confused by this and acceleration in Vista in general. I thought that the PowerDvd codecs were EVR compatible.... so in Vista Media Center you could use those for HD playback and get acceleration? Am I mistaken?

No joy, I'm afraid. You can clearly see this in graphedit if you try play anything MPEG2 with the Cyberlink codec. Connect to EVR and you get crude weaved deinterlacing and high CPU use, then try VMR9 and you get spatial-temporal deinterlacing with double the framerate and half the CPU use. Cyberlink can fix this fairly easily I guess - there doesn't seem to be any technical reason stopping them, and it makes PDVD an awful media player for 1080i MPEG2 recordings.

The h264 codec is definitely EVR compatible though, and _not_ VMR9 :-) The VC1 codec won't connect to anything else, so there's no way to tell. The MS VC1 codec is EVR compatible though (as is their MPEG2).

Are Quicktime H.264 clips accelerated by PowerDVD? Previous versions were by PDVD but with the 8600 GTS, Vista 32 bit I don't get any acceleration. Using Graphedit (or WMP) and the Haali splitter the machine locks up and doesn't playback Quicktime clips. Without Haali WMP and graphedit can't playback Quicktime HD (well they can't even with it, but without it it picks Microsoft's MPEG audio decoder.) PDVD can play it back but without any hardware acceleration.

Is there a particular version of Haali which is needed?

WMV HD (MS codec) clips playback fine with VMR with hardware acceleration ( as tested by GraphEdit).

Yes - 2% CPU on a 1.9ghz C2D. Makes sense, since it seems media file mode is EVR.

NVidia's hardware decoding side of things seems to be truly excellent - once the video actually gets to the card it handles pretty much anything. The main problems are in software, with wobbly drivers and the necessity for h264 acceleration to be rendererd via EVR.



Using Graphedit (or WMP) and the Haali splitter the machine locks up and doesn't playback Quicktime clips. Without Haali WMP and graphedit can't playback Quicktime HD (well they can't even with it, but without it it picks Microsoft's MPEG audio decoder.)

The latest Haali works for me, feeding into the Cyberlink decoders (for audio there are 3, use the one labelled "Cyberlink Audio Decoder"). You need to use EVR for acceleration as usual.

I dont think I'm quite in the console hater camp. Having said that IMO from a design & color stand point the 360 is a bit of an Eye Sore.

i can understand that. i use my 360 more for htpc stuff than gaming right now, but it's still the best solution imo (or any v2 extender for that matter). it may be a game console, but that doesn't mean the other functions are better than the rest of the competition. but to each his own.

even if the 360 cost $600 and all i used it for was htpc, it'd be worth it. i just don't want the headache. i mean look at all the posts of people trying to get a decent picture on theyre tv from theyre comp. after working for 8 hours, going to school for 3-4 hours after that, the last thing i wanna do is fix my "tv" when all i want to do is watch the game

After reading the entire thread, I think I got a little bug-eyed because I'm sure it's been answered, I just can't find it:

Is the 8500/8600 GT worth getting for someone who plans to use MCE 2005 right away? I know DirectX 10 will never be supported for anything other than vista and there will be full hardware acceleration come june but for right now, could I buy this, install it, and playback regular DVD's and such perfectly before the update?

Guess I'm asking if I can do everything I normally would be able to do right now (except of course for the hardware acceleration that's coming in june that really only helps with BR and HDDVD stuff)????

I think so, but anyway you are not restricted to playing within powerDVD itself. Once PDVD is installed you can play MKV/H264 in any EVR supported player (Like Windows Media Player or Media Center) and it will use the PDVD codecs and give you full offload to the GPU.

Latest patch fixed all this, Vista PDVD now accelerates MPEG2 in both VMR9 and EVR apps (ie PDVD itself, plus Vista MCE and WMP11)

I am using guru3d's 160.3 drivers, but in vista, my vista experience graphics and gaming graphics scores are both 1.0, yet it still is running aero. Does anyone know why my scores are so low? They are not the drivers because I did a clean install and with the official nvidia 158 drivers, the score was the same.

I have been unable to get 1080p out from my nVidia 8500 to my Sony 52XBR3, running Windows Vista. Any and all nVidia driver versions make no difference.

Here is what I have found interesting that I thought some here might have some feedback on. First off, this is the Gigabyte 8500 card purchased through NewEgg. I had my older nVidia 6800 based card so I decided to try that one instead. With the 6800, 1080p was detected right away and it works great.

So why does the 6800 display at 1080p but not the 8500? I know my 8500 can because if I use DVI to HDMI, it allows me to configure 1080p. It's just the analog VGA out that never gives me the option of 1080p.

Here is the key. With the 6800, Windows Device Manager shows my monitor as a "PnP Monitor." With the 8500, Windows shows it as a "non-PnP Monitor."

There seems to be some sort of enumeration conflict between this 8500 card and the Sony tv. Has anyone else experienced this? I tried to force it to a PnP Monitor driver but that didn't have any effect. Thoughts on how to get this to work out the VGA connector? Thanks.

That's the one that breaks BD I mentioned above :-( See the slysoft or cyberlink forums for others saying the same thing.

Unbelievable they still have such a severely broken patch up. Not only does it break BD, but it takes regedit and cleaning hidden files to get it to install in the first place (because PDVD's own uninstaller is so useless it forgets to delete lots of files).

Hi all - my first post so please forgive me if I screw up!
I'm close to purchasing an HP Pavilion Media Center m8010y and as one of the component upgrades, I thought I should choose to buy the "512MB NVIDIA GeForce 8500GT, TV-out, DVI-I, HDMI ". What I'd like to know in advance, and can't seem to find anything anywhere stating this clearly if it can do component video out?
Clearly HDMI would be best and I can do this direct to my Toshiba hidef TV - but I'd prefer to use my a/v receiver which can only switch component video. At this point, I really don't want to fork over the money for a new a/v receiver as I had enough trouble convincing my wife to buy this HTPC. So, simply stated, can I somehow do component video and if yes, what additional stuff (cables, converters, etc.) would I need to buy to make it work?

Sure it does - it's roughly the same for VC1/MPEG2 as the 7600/7800/7900/8800. On a C2D 2ghz, both are 20-25%.

Not fully for VC-1. All nVidia GF 6/7/8 series have the same VC1 acceleration (provided the GPU has functional Purevideo silicion as all GPUs based on NV40 6800 Ultra/GT have a broken PVP). GF 6/7 and the 8800 series also have partial H.264 support.

VC-1 acceleration on AGP GF 6/7 cards is a bit iffy, but H.264 works though it doesn't ofload as much as the PCI-E versions.

The Ati X2900 series is already out though no one's reviewed the video decoding performance yet.

the HTPC friendly X2600 (goes up to 1080p) and X2400 (this only decodes stuff up to 720p) cards will become available sometime in June.

where did you read that the 2400 only handles 720p content? I found nothing on ATI/AMD's site specifying that http://ati.amd.com/products/hdseries.html

I read on one website some speculation that because of the 2400 having a 64-bit memory controller that might mean only 720p decoding but nothing I've read specifies why it would only handle 720p if that is even true.

Any idea?

I don't believe that is true. There was an article on anandtech talking about the new 2000 series ATI's and they linked to an article that mentioned a 720p restriction... but I believe they were talking about the x1000 series.

I'll have to make sure of that. Does anyone know if the 2000 series drivers will support Windows XP out of the box? I have no interest in gaming - just HD playback. But, I'm not interested in moving to Vista until a lot more drivers are available. Hopefully, the XP drivers from nVidia for the 8500/8600 will be available when I get around to building my box sometime within the next couple of months. I'll be building it around a higher clocked Core 2 Duo, so VC1 playback shouldn't be a problem with either of the nVidia cards.
