i have two cards, nvidia gforce4 mmx 64mb it plays game fine but it doesnt do the ingame movies like first kiss etc.etc :/

my other card is a ati rx9250 128mb now with this it shows the ingame movies but theyre a lil slow, and bottom half of the screen has cut lines across it..

why doesnt it show on one and not the other? the rx is supposed to be a better card im told too but i cant seem to find stable drivers for it, i mean when i move or zoom in say the path goes all blue once i stop it comes back.. :/

i tried a few from ATI.com and ones on the cd but both did the same, soon as i stuck the nvidia card in the problem stoped :/

any ideas?

anyone?
