Choppy Video on VC1 MKVs
Hi folks,
Please advise me on best setup options to play back VC1 video.
Just ripped my Torchwood Season 3 (Children of the Earth) to .mkv with MakeMKV 1.4.8. The resulting .mkv files are VC1 video with DTS audio. This is actually the first VC1 video I've tried playing since moving from W7RC to RTM (32 bit).
When I play the files (via Media Center with Media Browser 2.1.1... because I'm having some difficulties with the recent 2.1.3 release), I get very stuttery video. Not the smooth play I get with AVC/h264. Lots of frames lost. Some investigation showed me that based on CPU demand of 50-60% during playback, I'm not getting hardware acceleration for these. I get acceleration for AVC/h264 files no problem (CPU use around 10%).
I recall when I set up my 7RC system, I had to set up the MPC-HC codec for VC1 to get them to play smoothly (I didn't use the whole MPC-HC player). I tried this tonight on RTM, and they are worse than running through WMC/MB. I get a few seconds of smooth video with apparent acceleration (~10-15% CPU), then the picture sort of freezes while the sound goes on. Sometimes I get garbage on the screen. Tried the same version of the MPCVideo codec I used on RC, as well as the newer August release.
FWIW, the disk image plays just dandy in PowerDVD 7.3 Ultra, with ~15% CPU usage.
My system is Home Premium x32 with a Sapphire 4550 card, Driver package version 9.10, and an Athlon X2 Kuma (7750, 2.7 Ghz) processor.
Help would be appreciated!

Note: I've got Haali splitter installed, but no other codecs other than the one W7RTM shipped with, and just now the MPC Video codec set for VC1 files only (though I turned it off after trying it). It's a very clean system right now.
