this is very frustrating.

I have a couple of vhs tapes that were recorded by someone else that look just fine when I watch them on TV but when I try to run them thru my ATI all in wonder card there's a bunch of squiggly lines!!

I've tried everything from taping the videos to another tape(which looked ok on the tv but got the same problem when running thru the card)
to making sure that "deinterlace" is clicked in my settings.

what's up with this?
any suggestions???
