It may be that your on board video card just can't cope with that video in
full screen. I have a SiS on board card that uses 32 MB of memory ( out of
512 in total) and it has problems with full screen video, particularly
video that has a lot of action/ is aimed at 3d enabled cards.

You can see which drivers the system has loaded  by doing this
in  a terminal:


In my case a number of modules refer to sis ( for instance sis_agp ) . I
suspect you will see something similar.

To sum up: I suspect a 16MB on board card just doesn't have the power to
cope with full-screen video unless the video file is quite
simple/undemanding graphically. Some videos play fine full-screen here,
with my SiS card,  while others don't.
