Well, we would need some log to understand that. Perhaps a matter with
the overlay functions of some cards, that do not support too high
definitions.

Well, I've tested HD videos (1920x1080)  on ATI and NVidia cards without
any  issues. This  is quite  CPU intensive  though (something  around an
Athlon  2400+  was required).  VLC  doesn't  have support  for  hardware
acceleration,  except  of  course  overlay (that  means  that  the  card
is  doing  the YUV->RGB  itself).  BTW,  I'm  not  sure there  are  many
acceleration cards able to decode HD MPEG2 streams.
