In order to get the MPC decoder to work, I unregistered qasf.dll. The MPC Decoder works with every BD I've tried except one... Planet Earth Disk 5. When I try to play disc 5, I get a black screen.

If I register qasf.dll again, Planet Earth Disc 5 plays (no DXVA though and 100% CPU). Planet Earth is 1080i VC-1 encoded video.

HTPC Specs:
OS: WinXP SP2
CPU: AMD 3500+ (Socket 939)
GPU: HIS HD4670
Catalyst 9.5

Has anyone else experienced this problem? Any suggestions?

MPC Video Decoder does not support interlaced VC-1.

Do you think Planet Earth Disk 1 to 4 is not VC-1 interlaced? MPC decoder works nicely for those disks.

Any suggestion for another decoder that supports DXVA for VC-1 interlaced video?

Disk 1-4 are progressive.

WMVideo Decoder DMO.

It plays using this WMVideo Decoder DMO but the CPU usage is 100%.
I tried the WMV9 Power Toy by Alex Zambelli to enable DXVA, but that didn't seem to work

PowerDVD/TMT are the best player/video decoder for interlaced VC-1 (supports DXVA fine).

Thanks I'll try that.
This thread also seems promising:
http://forum.doom9.org/showthread.php?t=144625

From that thread:

With this filter you can connect MPC Mpeg Splitter to Arcsoft Video Decoder which means you can get full dxva acceleration on ATI cards for both interlaced and progressive VC-1 video.

Works great on all the BDs I tested (using Zoom Player).

Where is VC1Tweak.rar?

Never mind. Found it in a later post.

I have my Planet Earth files setup as mkv with flac audio and decode it with the MPC decoder no problem. The only rip that gives me a problem is Sunshine, it gives a digital green screen over the video that flickers throughout the entire movie. I can decode it fine with ffdshow but then many of my other movies lag.

Any way of applying the ffdshow decoder just to my Sunshine mkv file and MPC to the rest of my movies?

The problem here is the lack of a decent free VC-1 decoder that supports DXVA (including deinterlacing), an equvalent of MPC - Video Decoder for H.264.

Just download a properly encoded rip, none of this interlaced nonsense. You own the disk so no-one should complain.

renethx, have you had any success with the VC-1 tweaks?

I spent a lot of time trying to get them to playback a MKV containing VC-1 1080i video. The best I got was CPU usage around 30% and a stutter every 3 seconds ... using Arcsoft decoder.

With my other mkv's (Kung Fu Panda, Black Hawk Down) Arcsoft also gives poor performance (CPU 30%)... MPC decoder gives awesome performance (CPU 15%)

The last option will be to convert to H.264

As for ArcSoft I am using TMT3 and this does not allow its decoders outside TMT3. So I tried CyberLink VC-1 Decoder (PDVD8) with 'CyberLink VC-1 Loader' (found in a thread linked in that thread). Unfortunately deinterlacing is very poor, but it works anyway.

TMT and PowerDVD are very good for interlaced/progressive VC-1 BD movies. What container is your Planet Earth 5 file? You can convert mkv/ts/m2ts to a BD folder/ISO by Clown_BD to play with PowerDVD/TMT. (Or TMT can play MKV directly, and PowerDVD too if you change the file extension to AVI or Divx.)

In the RAR archive, VC1Tweak_Haali allows you to connect to Arcsoft decoder.

I'm using a patched version of PowerDVD 7.3. I'll convert the MKV to ISO. I completely forgot about that option.
Should I upgrade to PowerDVD v8 or v9 for VC-1 deinterlacing?

No. Radeon HD 4670 + PowerDVD 7.3 Ultra is good enough.

Well nonsense compared with 1080p at 50fps. Interlacing is a relic from the days of CRTs that only serves to make things more complicated for LCDs. Admittedly a relic that got into the blu ray spec.

1080p at 50/60Hz is just a future technology. Those videos shot interlaced have to be deinterlaced somewhere whether you like or not...
