NVIDIA DVD Decoder

[Garyclaus16]

I have the retail version of NVIDIA DVD Decoder. I installed it and then proceeded to watch a movie with Windows Media Player 10 on Windows XP Professional on my A64 Machine. Everything on the machine is top noch blah blah...ND-3520A for the DVD-Drive.
I have the BFG Overclocked 6800GT 256 GDDR3 and whatnot.

I get no picture and no sound, yet WMP allows me to access the tracks, etc. I go into the settings for the decoder and it claims to be processing data as the compression meter is fluctuating as it seems to play the video. Basically it is playing but I am getting neither video nor audio.

I can play this with WinDVD just fine; however, I just wanted to use part of the functionality of the $400 video card-not to mention the $20 for the decoder. I have heard that the performance fo the pure video is superior to other decoders, as well. Anyone have any ideas? Thanks.

UPDATE: I tried it with zoom player and got this error: [NVIDIA Video Decoder].Video Output ---> [Overlay Mixer].Input0

Not all filters can connect properly. If the filter...

Did the trial run correctly?

 

[darkswordsman17]

Did you have the trial version on before this? I know that when the trial ran out on me, WMP would no longer play anything (no video and no sound) even though it was seeing the disc fine.

Maybe uninstall and try re-installing?

Hey everyone, sorry to resurrect a dead thread like this, but I'm having the exact same problems as this guy. Has anyone had problems like this and found a solution? I'm using a geforce 6600gt, and intel hd audio on an abit aa8 duramax.

make sure your trial hasn't run out then these procedures will work if done properly.

you need to increase the merit of the nvidia dvd decoder within the directshow filter hierarchy.

http://www.dvbviewer.com/forum/index.php?act=Attach&type=post&id=238

first download that program (called RadLight 1.2). then select nVidia video decoder (under the DirectShow Filters node) from the list, select MERIT_PREFERRED or higher, and click set value. Do the same with nvidia audio decoder. this should fix your problem. close the program and open your video. if it still doesnt work try rebooting and playing the video. this will reinitialize directshow. if this doesn't work you have more of a problem where filters conflict. you'll have to choose the filter in use (suppose it's intervideo or ligos mpeg2 decoder, etc.) and change that to a lower merit.

most likely the problem is that the nvidia dvd decoder only works with what's selected in its options. if you said prefer VMR9, you'll have to choose overlay if zoom player insists on using the overlay mixer to play it. if you can't get to the options of the nvidia dvd decoder, somewhere in zoom player there is an option where you choose your default renderer. choose the video mixing renderer and it should be fine.

Hey xtknight. Thanks for your reply. Unfortunately, I'm still having the same problems. Zoom player allows you the option to pick the video decoder, audio decoder, audio renderer, video renderer, and any additional filters. Originally I had the NVIDIA dvd decoder set up to prefer overlay, and I had the video renderer for zoom player set to be overlay mixer, and I got the same error that garyclaus16 had. I went ahead and changed the nvidia dvd decoder to "prefer vmr9," and I set video renderer to "VMR9 Windowless," and I still get a similar error. Do I need some sort of filter between the nvidia dvd decoder and the video renderer? I've tried fooling around with the nvidia video post processor as a filter with no luck. I really have no idea why this hasn't gone more smoothly, since this is a pretty fresh install of windows xp and I don't think there should be too many codec conflicts or anything. Thanks for all of your help so far!

Yep. I can't get mine to work with Zoom or WMP10. Tried suggestions as above.

uhhh have you guys tried the filter merit stuff? this WILL work if done properly. it's possible i made an error in my explanation but this stuff will work. every media player is based off of it.

EDIT: well oddly enough i'm having the same problem and i'm stumped. are all of you guys using 71.84 drivers? maybe there's an incompatibility. i noticed it was using DXVA B mode, different than DXVA A that it was using in the first PureVideo 67.66 drivers. re-registering the nvidia filters didn't help. the only conclusion i can come to is there's some driver incompatibility of my trial ran out (most likely).

i'm having the same problem as you tcrex2000. the video/audio decoders fail to connect to renderers (video card/audio card). the filter merit stuff isn't useless though. i recommend everybody set the nvidia decoders to highest merit so that other filters (not hardware-accelerated) are not preferred over hardware-accelerated ones. that will fix some problems, but apparently not a driver issue or trial run-out. if any of you are SURE your trial hasn't run out (i'm not), then we can confirm it's a driver issue.

i know i had these things working with the 67.66 drivers. i'll bet anyone $100 it's the drivers but i'm not convinced enough about purevideo to downgrade my video drivers when they fix another issue with my TV program. it's not worth it right now.

i just checked and my trial expired so i can't do any more testing. you can check by starting nStantMedia.exe under Program Files\NVIDIA Corporation\ForceWare\nStant Media. It will say right when it starts up if your trial ran out. If it says nothing, your trial is still going.

 

[xtknight]

sorry double post

Yeah, I'm using the newest WHQL drivers.

I've got a similar problem. My Nvidia DVD Decoder seems to work fine for actual DVD's, but for MPEG2 files, it just sits there and does nothing. The decoder icon appears in the system tray and I can access it as if the decoder were actually playing anything, but there is no video and no sound. Windows Media Player appears as it would if it were playing though; it displays the correct file length and all. What would cause this? Shouldn't I be able to play MPEG2 files?

It's an HDTV capture and it brutally slaughters my CPU if I try to play it without the decoder

Are you sure its working for DVD's? (You can see the NV icon in the tray during DVD playback?)

All these issues sound exactly like an expired trial, or using a bad key with the retail release. The decoder icon will show in the tray in both cases, yet the picture will not play.

 

[tcrex2000]

So, I went ahead and reinstalled it and now it works fine. I have no idea what went wrong the first time. Maybe try just reinstalling and it will help you. After reading rbV5's post, I suppose it's always possible I didn't enter my authorization number right the first time or something.

Yeah...the problem is actually a little different now. It turns out that my MPEG2 file might have just been bad - I re-ripped it from the transport stream with a newer version of HDTV2MPEG2 and it seems to play the video fine in Windows Media Player now, with the NVDVD icon showing up and everything. But there is no audio at all.

I did the thing the earlier poster mentioned about increasing the merit of the Nvidia Audio Decoder, and still nothing. I just popped in my X-Files movie DVD to confirm that it works fine, and it does - video AND audio. Why would just the audio not be playing (in the MPEG2 file)? The NVDVD control panel shows the video bitrate, but it shows the audio bitrate as zero, as if nothing were there at all. (And for reference, if I try to play the file in VirtualDub or something, I get audio - it just drops frames like crazy since it's not using the video card, I guess.) It does show the audio formats changing though (Dolby Digital, two speakers back to 5.1, and alternating between those and/or something in between)

Is it just a bad source MPEG2 file or what? But if so, how would I rip a "good" one from the HDTV transport stream? And why do I get sound from other programs playing the file anyway?

 

[rbV5]

Why would just the audio not be playing (in the MPEG2 file)?

Nvidia audio decoder is choking on the ac3 audio stream from the transport stream?

when my trial expired, filters would not connect meaning there would be no tray icon at all, either.

Perhaps...I'll see if I can figure anything out by messing around with different decoders or something

 

[SynthDude2001]

Bump, I guess.

I've been playing around with this stuff some more and I can't get WMP to play my MPEG2 file with audio....

Maybe I need to find some other MPEG2 files just to see if it's just a problem with my HDTV rip...(and are there any other programs that do this other than HDTV2MPEG2?)

Edit: I just played the original transport stream in Windows Media Player and the exact same thing happened. Decoder icon popped up, video seemed fine, but no audio whatsoever (except for the icon changing in the Audio Properties page). So that at least removes HDTV2MPEG2 from the equation.

 

[mkygod]

Bump for an old post. I got the same problem. WMP10 no video when playing dvd, though there is sound. The Nvdvd icon comes up and when i go to the properties, i can see the bitrate meter working, but no video at all.

i tried doing the radlight thing with upping the preferences, but still doesnt work. I am also using the 71.84 drivers.

 

[Tweaks R Us]

I tried the radlight alsp and it didnt work i have hte newest nv dvd decoder. my sound nor video works in wmp10 the tray icon does pop up also and hte bars are moving but no video at all. ive tried 71.84 drivers 76.41 and now i have 76.44. the radlight thing doesnt seem to be saving hte settings. i hit set and then close out open it back up and the setting is still set to merit normal.

 

[mkygod]

I think the problem maybe that some peoples trials have ended and so this completely disables the nvdvd encoder, even if you uninstall it and install the retail bought versions. That is what ive been reading in other forums, and im starting to believe it can be true, because my trial is over too.
