MP4 Playback Crashing 360 Extender Session

[mediaGuy 8]

I've been having an issue for about 2-3 weeks now where MP4 files (H264 and 2-Channel AAC) will kill my 360 Extender session when I try to play.  AVI and MKV (via Shark007) play fine.

The MP4s play fine locally and use the MF splitter (I even tried uninstalling Shark).

 

Here's some log info from a test, I don't see anything odd.  Basically the file looks like it's about to play and the extender session dies, bringing me back to the Xbox Dashboard.

Not blaming MBC at all, just no idea what's changed on the system and don't really want to format.

Does this happen on every MP4 file you play or just some? I get this problem intermittently, and all I can find out is that its not an Emby problem its a WMC issue. Any extenders experts care to comment?

Happens on every MP4.

System worked fine for years, now the last couple weeks it refuses to play (extender session closes).
