This is my first post on Creative Cow so take it for what that’s worth. I deal with this issue all the time with the GL1s I have at work, and I have been trying to get definitive advice on it at DVInfo.net. I find that playing back through the Canon cameras always works and that recapturing bad sections, as Matte said, works 90% of the time. Some people have had success after getting Canon to realign the record heads in the camera or using Panasonic tapes (not that either of these will help you right now, obviously). I imagine getting the camera that shot the footage is your only solution.
