Anyone know how I can get Premier Pro to capture using my ATI X800XT PCI-E card with built in ATI Rage Theater Video Capture?

Aside from this (and I may post this seperately), Anyone have some good advise for me on what type of stand alone video capture card is best? I need something that will capture 720x480 non interlaced, into MPEG-2, or Microsoft DV NTSC format? Normally I use Vegas to edit, but have used Premier Pro as well (I think I prefer Vegas).

Any help would be appreciated!

Thanks
