Extender (360) Can't See or Play MKV (SOLVED)
I have a quad-core with Windows 7 Build 7127 x86 installed. I installed the DivXTechPreviewMKVOnWin7.exe. On the computer, I have confirmed that MKV files play properly in both Windows Media Player and Windows Media Center.
I have set up Media Sharing in WMP to allow all devices to play media from my library. I then set up the Xbox 360 as an extender. The Xbox 360 connects to Media Center just fine. While MKV files show up in the WMC library on the computer, MKV files will not show up on the 360 library. Not a good start.
The next thing I tried was using Windows Media Player's "Play To" feature. On the 360, if you connect to Media Center, this will add the Xbox 360 Extender as a media device in Windows Media Player. So I tried right-clicking on an MKV file in WMP's library and Play To > Xbox 360 Extender. This does not work either, it just says "Contacting Media Server" forever.
To determine if this was an issue with just MKV files, I remuxed an MKV into .m2ts (AVCHD) using TSMuxer. The file plays fine on the PC in WMP and WMC. It also shows up in the WMC library on the 360 , and plays fine. WMP's Play To > Xbox 360 works with the AVCHD file as well. So it appears my Extender problems are related to MKV only.
Edit: Also, this is a fresh install of Windows 7. There are no third-party codecs , filters, splitters, or packages installed. Just the DivX Preview. The problems are happening with MKV files with AAC audio as well. I downloaded the Terminator: Salvation Trailer directly from DivX's Showcase site as a test file.
While it's great that the files are playing on the computer, the whole point of this (for me at least) was to be able to view them on my Xbox 360.
