Hmmm. I think you may need PureVideo 2 on your GPU to do interlaced VC-1 playback. The systems I'm using are 8??? series card with it. The 6??? series was just the original PureVideo.

Decoding issue, it's from retail BD's which I guess could be non-compliant but cuda decodes them fine. Freezes, blocky and green screen are some of the things I've seen. Check out the sample I posted last week in this thread.
PureVideo 2 or 3 is what's recommended for Blu-ray playback...

Vista 64 bit but still same issue with xp 64 bit on the same box, I dual boot on an X2 3800+. VC-1 software decoding performance is about 60% compared to tuned H.264 decoders. Should this be the case?
Well, the VC-1 software decoder there wasn't as tuned for interlaced as progressive, which could be your issue. The whole i>p conversion came in pretty late in Vista's development IIRC. I don't think anyone imagined software decode of BD-rate VC-1 back then; that was very much a DXVA scenario.

9800GT doesn't decode that clip either, it freezes.

Again if you can report to microsoft that their WMVideo Decoder included with WMP11 does not decode all BD's and point them to that clip as an example or let me know how to contact someone who will understand the situation.

I get roughly the same performance decoding interlaced and progressive VC-1 through directshow.

I've read the whole thread but I still don't get it...

Is this video actually supposed to be decoded properly with DXVA on ATI cards?

I'm asking because Media Player Classic Home Cinema on my Radeon 4850 with the latest drivers tries to decode it using DXVA VC-1 Bitstream Decoder and all I can see is junk:

click for picture

Same with Videolan Client , some pre 1.0.0 built from their nightly builds.

That suggests it might be a corrupted stream somehow. VLC is its own self-contained thing and doesn't touch the system decoders.

Does 1.0.0 include the new better ffmpeg VC-1 decoder yet?

It's your very own video.wmv from the the start of this thread.

I'm not sure about VLC's ffmpeg, it's a nightly build of 1.0.
Media Player Classic Home Cinema is 1.2.908.0

Here's the log file of VLC: http://savedonthe.net/download/111/videolanlog.txt

It looks like it uses libavcodec but there's no versioning on the libraries.

I've been doing additional testing on MPC HC now, and while initially I thought it doesn't matter maybe it does so I'm reporting it, with DXVA disabled MPC HC's screen starts to look exactly like VLC's screen, meaning it's like this: http://savedonthe.net/image/243/Clipboard02.jpg

I can't test if it works properly with windows codecs because I can't figure out where to download the codecs from. Media Player 11 won't install because I use Windows 2003, Expression Encoder seems to be willing to save in VC-1 format but the codec is not available to MPC HC, when I disable both internal filters, the same with Windows Media Encoder...
