I have been having real problems making good copies of several homemade DVD slideshows. My main computer runs XP, Plextor 712A burner and Nero burning software. Can someone give me a step by step list of how to successfully burn good copies. I am burning a lot of discs, but most are unusable. My originals play very well, I just simply want to "copy" them. Seems simple, but not for me. Thanks for ANY help.
