I have
Clone DVD 4.1 and Roxio Basic V9. I back-up my DVDs and burn them without error. The problem is that when I go to playback the DVDs, the DVD starts normal and will play through the previews and the title menu. I can access the special features ect.... but as soon as I try and play the actual movie it stops playing and freezes. I have tried to use different types of media and players with no success. I have also tried several diff. movies. The issue only seem to be with the more recent DVDs I have purchased, only movies have no problems.... Has anyone else encoutnered this??? By the way I am running windows vista. Thanks for your help.
