Writer (DX9.TextureAVI) strange behaviour on different PCs

Hi all,

could you tell me what the difference between those two AVIs is? (besides the framerate) Both were recorded within the helppatch of the same vvvv release on two different machines, both running win7 latest updates.

Both videos can be watched on both machines in windows media player.
BUT:
I can’t play the video from B on both machines within vvvv. Regardless if i use filestream, filestream2 or filestream VLC. The video recorded on A works on both machines.
