I'm trying to play a .mkv file (created with handbrake) in Windows Media Center.

  • I'm running Win 7 x64
  • I've installed haali media splitter (file: MatroskaSplitter110109)
  • I've installed ffdshow tryouts (file: ffdshow_beta6_rev2527_20081219)

GSPOT says the codec is MGEP1 and that "Codecs are installed"

Below is what MediaInfo has to say.

When I try the file in WMC, it doesn't play. What do I need to do to get this to work?

Install the DivX Plus Tech Preview of MKV on Windows 7; your file is perfect because it's H.264 video, aac audio in MKV, which I te same as DivX Pkus HD. It's totally free, and more info is at http://www.DivX.com/en/windows-7 and labs.DivX.com

Seems to work for video. Some MKV's don't play audio. –  Scott Weinstein Dec 14 '09 at 2:05
    
Intalling ac3filter helps for files with Ac3 audio (ac3filter.net) and users in the labs forums have found some tricks –  Porfitron Dec 14 '09 at 2:15

Try to install Haali Media Spliter, which is pretty much the official codec for opening MKV containers and now supports both 32-bit and 64-bit (since December 19, 2009! The version you listed was only 32-bit). Note that Haali only "opens" the file, or container, it does not read the audio/video content.

So if Media Center seems to try to opens them now, but still can't play them, maybe you miss the proper codecs to play it. To handle this, install the ffdshow experimental 64-bit codecs. The 32-bit ffdshow tryouts that you listed will only work with 32-bit players.

Don't forget that you can configure ffdshow (in Decoder configuration) to tell it which type of content to read or not to. This provides you fine grained control over any compatibility issue.

Btw, gspot possibly only look at 32-bit codecs to determine that you have all codecs installed, and could therefore be wrong in this situation. It's really two universes side by side...

Windows Media Player and Center will not play MKV files without some extra work. You'll have to install the x64 registry file from this site. You can skip the first two steps. Just install the appropriate registry file. MEdia Center will now be able to play MKV files.

Tried both reg files. No dice –  Scott Weinstein Dec 14 '09 at 1:17
