High profile .m4v works great
I'm sure this has been hashed out elsewhere, but a quick search of the forums didn't yield an obvious answer. This may be a basic ignorance of video encoding-decoding. I know that the xoom does not like high (or low?) profile h264 MKV files. I took a movie trailer (1280x720) in the MKV wrapper (high profile h.264) and of course it played like garbage on Moboplayer (or smoothey on rockplayer but no sound). I used hand brake and converted it to a high profile h.264 mp4 file with the original resolution (the output extension was .m4v) and the clip played like a charm.
So is the issue with the high/baseline profile of the file or the container its in or both?
Could a codec be optimized for the tegra2 chip to play high profile .mkv/h.264 video?
Sorry if I'm coming across as an ignorant buffoon but it seems like I have read ideas that go either way.

The profile itself doesn't actually mean much. While the 3.1 update did improve video support slightly, the Xoom was already capable of playback of high-profile video.
