I am trying to burn a dvd from a canon dv video camera. I can transfer the video from the camcorder to the computer via my firewire but i notice that once the file is on the harddrive it has some scenes where the picture shakes. It is usually in spots where people are moving quickly (hand gestures, shaking a head). Any ideas what is causing this? I have burned it to a dvd and obviously the shaking problem is also on the dvd.
