I still had the problem since Version 2 that MP4 and M4V files will not play correctly.
The files are encoded with different software ( handbreak and XMedia Recode ) but all of them use flexible fps.
If you play a Movie it looks ugly.
Since then I use XBMC to play the movies
Please investigate in this error and kick the bug ass …
When I come home she is sleeping and I can’t start the TV but on the weekend … to short up all things here some details and you’ll get a private message in a few minutes where you can download a mp4 file.
