Leadtek gf4 ti4400 ....full screen video sucks!!?!?!

Ok i had a hercules gf3 ti200 for a bit and it played movies wonderfully on my monitor (1600x1200 19"). Everything from divx to dvd to svcd.

Now i upgraded to the leadtek and it sucks, as soon as i bump the film to full screen it chugs really really badly and is unwatchable. I have tried all the drivers ever supplied by leadtek and nvidia and no joy. It plays games no problem and whizzes along with high frame rates etc.

Any suggestions (i have tried it after a reformat too)??

how can a geforce4 perfrom that bad. test in on another system. try yr old card again and see if the same thing happens. run 3dmark and see if yr geforce4 score extraordinary low scores. if it does, RMA it.

the card scores over 10k on 3dmark...as i said games are fine, just video.

hmmm wonder if it's a codec problem??
