Fails to play (some) 720p MKV content

Hi,

I'm running XMBC on ATV2 for a while now, but lately I have more and more issues to play 720p MKV content. It just crashes and goes back to the ATV menu. I hope you can have a look to see what is going on. In this example it's just a regular 720p HD rip of a TV episode.

Platform: ATV2, iOS 5.0.2 (4250)
XMBC: v11.0 (Compiled Apr. 1 2012)
Skin: Aeon Nox
Logs: XBMC Debug Log | Sys Log | CrashReporter


Thanks!
