i have been using Clone/Anydvd for some time now and have never had a problem. I have always used my laptop for my backup needs. Today I installed Clone on my desktop and the process worked fine but the DVD will not playback on certain stand alone players. I have tried several players in the house and it will play on certain ones but not all. I have never had this problem in the past. The back up copies have always played on all DVD players that I use. Why would it just start today when I move to a different computer? Could it be the actual burn itself?
