I've been burning DVD movies for quite a long time now (either from home movies or backups). However, lately, my "copies" are skipping/freezing. I have a few stand-alone dvd players in the house and the freezing/skipping are occurring in the same places (therefore, I've ruled out the players themselves). My burner driver is up to date. I've been using the same type/brand of media. I've also tried reducing writing speeds but still no luck. Multi-tasking on my comp is not an issue -- but tried shutting everything down before burning and still no go. On occasion I'll get a copy that is fine. Hmmm?? I don't think that it's a software issue. Maybe computer dvd burner need a cleaning? Need the help. TIA.
