A lot of dropping frame

Hi, I've got a problem, see the attached Instrument and log files. There are a lot of dropping frames when playing causing the framerate go down to 9 FPS.

I test, too, with VLC on my AppleTV and I've got the same visual problem with many movies (1080p ones). I made a last test with another player on the AppStore, with the same file and no problem with playing these movies.

Thank you for your help. PascalArchive.7z
