I was transfering video from my camcorder to my brother-in-laws PC via USB the other day. When we finished the capture, there wasn't any sound. Any ideas on what could have happened? We were using the video capture feature on Roxio Easy Media Creator 7. I always transfer video to my PC via firewire, but he doesn't have a card for it, so we are stuck with USB for now. Any ideas or general things to check out??
