Nvidia GeForce GTX 460(GF104 GPU) supports full audio bitstreaming - Page 54

Uhh, I said audio SETTING, not audio TRACK! Right click while the movie is playing, go to settings, go to audio, and change it to primary HD audio or whatever it's called. Been a while since I used PDVD.

You have to change the audio output option in the PowerDVD preferences window, not the language tracks. This option for outputting undecoded audio only shows up when you're playing the disc.

Right, that's what it is. Non-decoded HD audio. And as I said before, if you play any non-Blu-ray disc, you will need to do this again when you play another blu-ray. The option doesn't stick. Idiots. (Yes, we've asked them to fix it since PDVD9. Here we are with PDVD11 and it's still not sticking.)

Okay, I understand now. While the film was playing I went to the Settings section, for Speaker Environment I made sure it was set to "Use HDMI", but when I went to Output Mode only one option was available "PCM decoded by PowerDVD".

Make sure PDVD is updated to the latest version. Make sure you are using the latest nVidia drivers. The 460 is one of the bitstreaming capable cards, right? I have a 450 so I don't know for sure but I thought the 460 was one of them.

According to the title of the thread it is I'll make sure everything is up to date. Thanks for your help.

I know it SHOULD be but you never know. Yea, just make sure everything's updated and see if that helps.

Just a little update on my GTS 450 to GT520 swap. I am back to using the GTS 450.

The GT520 worked fine for everything but PDVD 10 3D/ISO/DISC bitstreaming. I could bitstream M2TS files, but any "disc" I could not. MPC-HC w/ LAV or ffdshow worked fine regardless of source.

I didn't test this exhaustively - I just wanted to watch Imax Deep Sea and bitstream. What's odd is that it would bitstream all non-HD audio (DD or DD+ worked fine, and these formats are used at the beginning of the several IMAX 3D titles I have) but DTS-MA or THD, no go.

Swapped back the GTS 450, everything back to normal.

After much updating and tweaking and what not, I finally figured out the issue... I needed to have the check box for Allow applications to take exclusive control of this device selected under the Advanced tab on Nvidia's HD Playback Device properties. As soon as that was ticked I was able to see two other options in PowerDVD for the HDMI Output Mode. I selected the Non-decoded HD audio output mode, and TrueHD is now displaying on my receiver. Thanks so much for all the help!

Just out of curiosity, does anyone know if selecting the other check box for "Give exclusive mode applications priority" is recommended? And my current sample rate is set at 24 bit, 48000 Hz, should I stick with that or select 192?

cyberlink released a new patch a few days ago thats supposed to improve compatibility with the new nvidia drivers

Yes. Is there a reason you disabled those checks in the first place? They're enabled by default. It is a good rule of thumb not to disable anything that you don't know what it does.


There is no demonstrated audible benefit of going higher than 48, but if you have original content higher than 48, then it won't be downsampled (but upsampled to 192kHz). There is likely no discernible audible benefit for that either though, unless you're a bat or a dog.

There are at least two real downsides to setting output to something that high that I've encountered (may or may not apply to you). One is that most receivers can't apply DSP like room correction to such signals (Onkyo 606/706) disabled DSP for anything higher than 48 for ex.). The other is that more processing power may be used. It is usually negligible, but with a certain Ati card for instance it was enough to raise the GPU's clock from its idle state. With Nvidia you probably don't have this problem being that it doesn't keep the stream open when no sounds are produced (the "silent stream" bug).

Good point, and I usually do just that. I believe I unticked them following a guide for setting up an HDMI playblack device. They also suggested to untick full-range speakers if you have small speakers, untick all Enhancements, and set bit rate at 48 kHz.


All of that makes sense. By the way, is there a work around for the silent stream bug? I remember a couple people talking about the issue earlier in this thread.

Anyways, next time I'm messing with something I'm not 100% clear on, I'll run it by the forum and see what you all say first.

Thanks again for all of the help.

I have Zotac GT440 with me, though the specifications on the box says it bitstreams DTS-MA. and DD THD, but i have not seen any member here confirming that they are using 440 with actual bit streaming ...... any one who can confirm this ...

SamuriHL,

I've been a ATI user for over a decade now and thinking of switching over to Nvidia. Is your Nvidia graphics card to your likens now? Everythings working fine? thinking of getting a 460

I'm gonna get a new video card for HDMA 1.4a support and currently with the last 2-3 ATI driver updates I've been getting blue screen of deaths or Windows7 start up problems every now and then.

ATI 5670
Window's 7 x64

I can't confirm it from personal experience, but all 4xx series up to the 460 can bitstream. Only the faster cards, 465, 470 and 480 cannot.

I have been using Sparkle GT 440 for a long time. HD audio bitstreaming is no problem. Every GeForce 4xx/5xx up to 460/560 Ti supports HD audio bitstreaming.

Yea, I know the quirks of my particular setup and have settings that work around them quite nicely. I use custom resolutions to get extremely smooth video. I'm using MC16 with LAV Filters, LAV CUVID, and madVR. This config allows bitstreaming and auto refresh rate changing. Man it's awesome. Yea, I have no complaints with the 450 at all.

do you or would you have some sort of software install guide(MC16, LAV filters, LAV CUVID, and madVR) for your 450? Would this card do well using TMT5?

thanks in advance

Check out the J River forum. There's a LOT of info there. Yes, TMT5 works brilliantly with the 450, as well. MC16 is currently in the middle of working out a new feature called "Red October" that automagically just works. It configures all the filters that have been vetted by the beta team for use in the "J River codec pack". That gets automagically downloaded for you when you install MC16, and does NOT influence your currently existing codecs. Pretty sweet. I simply use LAV Splitter, LAV Audio, ffdshow raw video, LAV CUVID, and madVR. You can set those per file type in MC16. It's pretty awesome.

Yikes, did you check if it was opposite day when they put up the guide? Normally when you have a receiver (even more so an HDMI receiver) just let Windows output the 8 channels untouched (full range) and let the receiver deal with bass management.

I don't think so. It may or may not bother you. Some people don't even notice it until it has been pointed out, others do come and ask specifically about that issue, not knowing that it's already well known here.

Oh jeez. okay, well looks like I'll be correcting that too then. Thanks!

Yeah, its a little irritating, but nothing I can't live with.

OT but, what are you using ffdshow video for instead of lav? Does it not work in jriver or is there something it does for you.

Also I've been contemplating checking out jriver the past few weeks since you mentioned it. How would you compare it to xbmc, wmc/mediabrowser? I really like how I would be able to incorporate lav filters, madvr, lavcuvid in to native player, but how are the media center functions and plugins, interface etc.

ffdshow raw video filter (different from ffdshow Video Decoder) is used for post-processing/subtitles/motion interpolation (with AviSynth/SVP), inserted between decoder and rendrerer. Well, it's actually the same as ffdshow Video Decoder without "codecs".

Splitter -> decoder -> ffdshow raw video filter -> renderer

Ok I see.

In regards to a GT 430

"The card mostly lost points for multi-cadence incompatibilities and compression artifacts. Losing points for some of the obscure multi-cadence tests, like 12 FPS animation, isn’t much of a concern for most folks I think. And while it’d be nice to have the graphics card fix compression artifacts, this is only a problem with poorly encoded or low-resolution source material. Neither of these issues is going to affect an HTPC user who wants to watch movies on Blu-ray."

I dont really understand what "multi-cadence incompatibilities" means. I am only using this card for TMT5 for blu ray playback w/ bitstreaming and occasionally foreign DVD's. This card should be more than sufficient correct?


Newegg has the following for a ridiculous low price.

EVGA 01G-P3-1430-LR GeForce GT 430 (Fermi) 1GB 128-bit DDR3 PCI Express 2.0 x16 HDCP Ready Video Card

The cadence patterns test the ability to detect, and therefore properly deinterlace, specific types of content. That said, the issue highlighted above is no longer an issue - NVIDIA addressed cadence detection a couple drivers ago.

Thanks for the quick reply.

$20 for a new GT430 will be great for my htpc then.

Are there any news on 5xx series mid-range cards, like a successor to the 440/450, something like a 540?

The 520 is sadly too slow for serious HTPC usage.
The 550 is a gaming card, overkill for HTPC.

So what fills the gap between those two?
Give me a 540!

http://www.digitalversus.com/recycli...ews-19382.html

So, as the preview author says, the 530 should be a succesor to the 430 or is pretty much the same thing. The versions of the 545 is something like 440/450, maybe something more in between of these. IMHO, Nvidia now has pretty much the same as AMD had long ago, exactly Nvidia now has the analogs which were missing before like the AMD's 5450/6450 it's equal to the Nvidia's 520 now and so on. In your case I coudn't even tell what to chose, because I don't think the 545 can be compared to the 450 because it's succesor more likely is 550 which is kinda expensive now and I would go with the 460 instead. I don't really know what to do know (pretty much the same situation here), perhaps we have to wait for some time and then see if these 545's are worth the attention or maybe just grab some 450/460 which now can be found for quite low price and just enjoy. That's just my thoughts and I might be wrong.
