iTunes 11.0.3 / Quicktime 7.7.3 / WindowsXP sp3 with DirectX 9.0c


Our couple of XP machines are having problem playing MP4 video.

Apperentry It is common DirectX video acceleration problem.


One machine plays choppy, another machine show nothing.

All files are very small and with VLC, CPU usage is like less than 30% playing without problem.


I cghanged video setting in Quicktime and no effect.

Probably video accelaration setting  is not synced between Quicktime and iTunes.

How can I fix it?
