4456	Internal player playback with stutter/pixelation for matroska/H.264	Mike Rice <mikerice1969@…>	Isaac Richards	"
When I try to play this type of file with the internal player (just tried again with SVN 15409) I get lots of playback problems and errors like this:

2008-01-10 13:49:04.205 GetNextFreeFrame() served a busy frame G. Dropping. LuLuLuUUUUUUUUUUUUUuUuuuuuuuuuu
2008-01-10 13:49:04.205 GetNextFreeFrame() is getting a busy frame P.       LuLuLuUUUUUUUUUUUUUuUuuuuuuuuuu

2008-01-10 13:49:04.444 GetNextFreeFrame() is getting a busy frame P.       LuuuuuuULUuULUUUUUUUUUUuuuuuuuu

default options to mplayer and ffplay (SVN 11051) play the file fine. 

Mplayer says:
