For you intel guys.

And info on those who have issues with Denon Receivers:

Very good reads...

That's definitely Archibael's blog. Sounds very much like him. Archibael, is there any luck on the front to accept Denon's intepretation of the spec? If Intel fixed this I'd buy the G35 or G45 in a heartbeat.

I thought it might be. I've been following the G35 thread pretty closely as well.

Yes. Anandtech's write up of the NVIDIA 780a (which has the same IGP core as the 8200) says so. http://www.anandtech.com/cpuchipsets...spx?i=3305&p=2

NVIDIA integrates their PureVideo HD capabilities into the 780a. PureVideo HD offers hardware acceleration for decoding VC-1, H.264 (AVC), WMV, and MPEG-2 sources up to 1080p resolutions. Advanced de-interlacing is available when using a Phenom processor.

I don't know what you're talking about; I don't know who this Brezenski guy is. Seems like quite the blowhard, though it appears his heart is in the right place.

Not heard anything, yet, alas.

So I took the plunge and bought the ECS board and installed XP on it. The install and updates went smooth, but video and audio playback has been frustrating to say the least.
At first, I was unable to get the nvidia HDMI audio device to show up in the device manager, until I first installed the IDT audio drivers. I did manage to get that working. However, the unfortunate part is that pretty much all playback stutters slightly (regular dvd, mp3, 6 channel FLAC i created from a TrueHD source with eac3). It doesn't seem to be a CPU issue, since it never gets above 30%, so I can only think the drivers are potentially in worse shape in XP than vista. I have tried the 174.74 (have to double check), 175.16, and 175.70 and drivers but they are all pretty much the same. One thing I haven't tried is using the onboard audio instead of hdmi to see if the stuttering goes away.

This brings me to another strange behavior. When I select 7.1 channel configuration in the control panel, all PCM files are sent to my receiver as 7.1, including stereo and my multichannel FLAC file. However, if I select anything else, including 5.1, they are sent as stereo.
Furthermore, when I play my FLAC file with the 7.1 channel configuration selected, I get sound out of my back surrounds, but not my side surrounds. The other channels seem ok though. So this brings me to a couple of questions, specifically for some of the g35 experts.

When you play a 5.1 track, does your receiver light up as 5.1 or 7.1? (Question applied to both Vista or Xp).

Are there many people who have the g35 working well in XP? I searched the thread somewhat, but hopefully those who have followed it more closely than I can point me to some key posts.

The nvidia guys have taken the position that they will get the video acceleration and such working in Vista first, and then eventually get it to work under XP. If you go the nvidia route for hardware acceleration, you should be prepared to accept having to use a Vista environment to make it work, at least for the next few months. They have some issues with getting things to work well at all (the usual nvidia issues with video and drivers and purevideo), much less getting it to work on 2 platforms.

hey cghebert, thanks for the feedback.

1. If I remember correctly, You must Turn on some "processing" on your RX-V661 in order to get 6 to 8 channel upmixing, (Like Dolby Pro Logic IIx).
by default, you aren't suppose to hear side surround speakers.

2. I would really appreciate if you could post some Print-Screens of the HDMI Audio Options under WinXP..

Yes, I feel somewhat like XP might be a lost cause, but if it comes to vista I might just be better off with a ps3. Vista ~$100, plus board $70, plus BD drive ~$120 vs. ~$300 for PS3 with a good deal, plus potentially no headaches or waiting for drivers to come out, and I could even play games on it. I'll have to read up some more on the ps3 though.

1. Yes, this is the case. However, it looks like that since it already "thinks" it is getting a 7.1 channel signal, it doesn't activate PLIIx when I try to enable this feature. PLIIx works fine with a 5.1 dolby digital signal though.

2. I can when I get home, but there really isn't much in the way of options. It really doesn't look any different from a standard audio codec from what I can see. Some of the g35 folks might have more of an answer though.

G35 doesn't support HD playback with XP. It's a shame.

I believe that is more of a PDVD issue. IIRC, some have TMT working on a G35 under XP with the JP renderer files.

However, if you want to be at the leading edge, you should be using Vista.

No, it's a driver issue with G35.
Vista has weaknesses that I'll not go into here, but there a good reasons to not use Vista. And it has nothing to do with being anti Microsoft.

The spec is that you shouldn't hear the "back surround" since the side surround are the traditional "surround" channels.

If you are trying to build an HTPC to save money over a PS3, I can't say you'll be happy. Perfect blu-ray playback with all the advanced audio codecs and profile 2.0 for under $400 -- out of the box with no tweaking? PS3.

I've got 3 HTPCs but still end up using the PS3 for anything it is compatible with. It just works and looks and sounds great. And it was cheaper than each HTPC.

Of course, you can do MORE with an HTPC, which is why I have them. But for what the PS3 does, it does it better, imo.

Got 7.1 Multichannel working, but the video still has issues. PowerDVD seems to trigger the problem. When I install 7 or 8 the stuttering returns and my audio begins to act up. But once I uninstall PowerDVD and reinstall all the nvidia drivers the multi-channel is fine. Installing my 8500GT automaticly causes the stuttering, so for now no Hybrid SLi. I did have success with Hybrid SLi using the 175.16 drivers. But this feature doesn't quite work like I had hoped. If you choose to use it for Boost, only the onboard display outputs are available. I need two dvi outputs so I am forced to use the Additional Monitors mode, which is fine since the 8500GT is powerful enough to run Blu-ray. Can't wait until the drivers are sorted out. But for now I will enjoy stutter-free 7.1 Multi-channel music.

That's silly.

I have a G35 with TMT and it works perfectly. Full HD sound, full HD picture.

And vendors are developing drivers for Vista first, especially for HTPC stuff, and maybe not for XP at all.

To make a statement like you did, it has everything to do with being anti-Microsoft. There's no reason to avoid Vista nowadays. (And anti-Vista should be taken to another thread - I'm pointing out that it works perfectly for a HTPC setup).

Were you able to get 23.976 working smoothly in the meanwhile? That's the only thing holding me off from buying considering a G35/G45 mainboard.

No, but it doesn't seem to matter. Something is doing the 3:2 (or reverse 3:2?) pulldown properly. Given how many people have the G35 working, I'm thinking it's the G35 or TMT/PDVD, and less likely each of our displays.

Even with 24p, I'm not sure how valuable that would be if you also plan to play 1080i material, as you'd have to constantly switch between 24p and 60p? I guess there are some utilities that might work for that.

Anyway, I'm VERY sensitive to judder, and there is none when using the G35 at 60p and viewing 24p material. Suggest you get a good enough CPU to turn HA off though, as I tend to get the best results on all video formats with HA off (I use a Q9300, which is overkill).

I find that strange. If the G35 outputs 60Hz then technically there's no way for it to undo the 3:2 motion judder.

With movies there's no need to. The DScaler IVTC mod plays all my MPEG2 1080i60 sources very nicely in 24p. For video content the situation is different, of course. But I have to switch refresh rates all the time, anyway, cause I have all kinds of refresh rates here (24Hz, 25Hz, 50Hz, 60H).

Don't be angry with me, but this is technically not really possible. If the G35 really outputs 60Hz then the output MUST contain 3:2 motion judder. This judder is very minor, though, and many USA people don't see it cause they're simply used to it thanks to years of "training". It's different for me. Living in PAL land, I'm sensitive to the 3:2 judder, as minor as it might be.

Give my fix a try.

I fixed my DVD playback issue again (I think), and managed to fix playback through VMC. There is a small program called VMCC.EXE that can change your default Vista Media Center codec. I currently have a demo of TheaterTek installed on my computer, which installs an nVidia codec (it will be interesting to see if this is still available to me after the trial is up). I switched my video and audio codec to the nVidia one, and I can now play DVD's in VMC.

I also read that the nVidia drivers have a horrible time with multi-threading for you multi CPU folks such as myself. This apparently can be fixed two ways, you can change the affinity, or you can bump up the processing (have no idea why this works) in the nVidia control panel. You need to go into the television color settings (the one with the inverse telecline check box) area and bump up the edge effects and what ever the other one is to 25%.

Doing a combination of these two "fixes" seems to give me smooth playback with regular DVDs (and they look beautiful).

You have really have now idea what you're talking about. Vista is great for most people, but for some it's not a good choice and there are solid reviews/tests that support that. It's always a good thing not to make general statements and accusations on issues you don't have enough knowledge about. Sorry about off-topic.

Isn't that the entire point of 3:2 pulldown? It's certainly undoable by the display and/or the source device?

In any case, perhaps there are degrees of motion judder. I see it, although it's subtle, when things are incorrectly configured, and I don't see it on the G35.

If you really need 24p, then you'll have to wait for a driver upgrade.

Howefver, if you want HD video at 1080p and full HD audio, all over HDMI, then right now you have no choice but the G35 (as the 8200 doesn't seem to work yet, except for that one guy).

I don't know any source device or display which can undo 3:2 pulldown from a *progressive* video stream. There are several source devices and displays which can detect a 3:2 cadence in 1080i60 content and convert that to 24p. But none of them can do that for 1080p60. There's one lonely video processor which can do this and that is the iScan VP50.

Totally agreed. I want to go Intel CPU in any case. So the question for me probably is G45 or MCP7A.

For what it's worth, you can set the G35 to interlaced, but then the PC display looks a little weird (typical interlacing flicker on movement).

In my experience setting HTPC to interlaced output doesn't really work well. I think the renderers are converting everything to progressive and then the graphics card slaughters that for interlaced output.

I may be having issues with the LG BD/HDDVD: I get an error "your video output device does not support playback" (or something to that effect) in NERO 8 when trying to playback a physical BD disc (HDCP?), but not BD's ripped to the server. Anyone have any ideas? In the bios under SATA drives there is an option to enable either SATA or ACHI- would that have anything to do with it? Or do I need AnyDVD running in order to view ripped BD's?

Playing BD from the folders does work as I mentioned, but my CPU usage is at 60-70% (AMD Athlon X2 5600+) and depending on the movie, the stuttering is very noticeable. On "POTC: Dead Man's Chest", the stuttering was the worst and the movie was unwatchable; on "Before the Devil Knows You're Dead" it was much less noticeable but still there.

As far as loss-less audio over HDMI, I'm not sure how to select audio stream options from a ripped BD movie so I was not able to try it last night. I was definitely hearing great-sounding DD 5.1 surround, but only at the standard 44.1 KHz sampling rate according to the receiver.

Quick questions, do you need to still use powerdvd to get HA with this board?

Does the receiver need to support HDMI 1.3 in order to receive and play the uncompressed 7.1 audio?

HA is sketchy, which is why a good CPU is a good idea. TMT improved HA on the G35 with the recent update, but it's still not perfect. In any case, it runs fine without HA.

LPCM is HDMI 1.2 (and I think 1.1), so you don't need 1.3 to get it.
