Yes, using VDPAU. Bizarre though that it's the first time I've seen
this in just under two years. Is it just that the DVD's written

On a separate note: besides just testing them myself, is there
anything that will will benchmark a setup and say your best best for
this card is this playback profile and this deinterlacer?
