This is hrev43830 (gcc2hybrid).
While older revisions had no (or very few) problems playing 720p videos in MediaPlayer, they now continually stutter and even stop for a second. Sound runs without stuttering in-sync. This is on a Core2Duo 2ghz, 2gb ram, nvidia 7600 Go (using the nvidia driver).
I can't say when exactly it started, I'll embark on a binary search soon. I happen to have an alpha3 installation handy, where it plays without problems. While it's difficult to assess, "top" suggests a CPU usage of about 25% in alpha3 and 35% in hrev43830.
Attached is the ouput of media_server and MediaPlayer when playing the first few seconds of a clip "720p.mkv".
