.MOV Movies Jerky

I recently installed aTV Flash on my Apple TV 160 gig. When playing my .MOV movies I noticed the picture is jerky, like there are frames missing. Here’s an example of the stats on theses files:

H.264, 1280 x 720, Millions
Linear PCM, 16 bit little-endian signed integer, 2 channels, 44100 Hz

Data Rate: 24.77 Mbit/s
FPS: 30
Data Size: 85.9 MB

Any assistance would be appreciated.
