I purchased a Sony DCR-TRV8 camera a couple of weeks ago but can't get it to work with my iMac DV SE. At times it will work, but other times it won't. I use it with iMovie of course, but I turn it on, and it sometimes will connect for a couple of seconds before disconnecting. At other times, it won't connect at all. I know it's not the camera because it worked on an iMac at Compusa. I've tried different cords and have talked to different Apple guys. I've re-formatted the hd and tried everything that I can think of. Any ideas?
