I'm sure this is a very simple fix, but can't get my head round it. Show copied from VHS to DVD +RW on standalone recorder. I'm trying to get it onto my hard drive to edit out commercials and other junk. Plays great on PC but, when ripped, only plays back first few seconds (anything from 7 seconds to 1 minute). Using DVDdecrypter, Nero Express 2, Tmpeg DVD authoring.......you name it, I've tried it! Any ideas appreciated.
