I think the best capture cards to get if you are working on a pc are either the DV Raptor or DV Rex from Canopus. I bought a turnkey system and have actually given up on asking them for tech support because the online Raptor forum is so helpful and so quick. Check them out at http://canopuscorp.com. Check out the user forums....(posted 8970 days ago)hope this helps..
