Jerky fullscreen video playback

Hi everyone,

I need to play fullscreen videos in my game.
For it I create a video in ogg Theora 720p format and I apply it via a MovieTexture on my GUITexture.
However the video rendering under Unity (in any way I choose import parameters) isn’t smooth (video appears a bit jerky on camera tracking moves for example) while that is not the case when I watch it with VLC or Media Player Classic.
It’s just like some frames being skipped during video playback.

Do you know some tips to avoid this problem (compression settings, tool…)? Must I wait for a hypothetical update of the Unity video playing engine?

Thanks for your help.

Do you think this may have something to do with it?
