AFAIK, -vo gl never worked or will work on NVidia cards, it was desgnied for 
SUN workstations with hardcore grahpics cards.

-vo gl2 always works on my Nvidia tnt2 ultra, but if yours is crashin,
then a gdb backtrace + full bug report might help...


As for teh DVD problem... who knows
try -ac null or -nosound and see if the jerk is gone if so - > ac3 problem?
anyways its worht a try?
