I am trying to burn movies with Nero. It's failing to burn. I tried burning an ISO with UltraISO. It's failing to burn. MagicISO works. Could it be that I have to disable Vista DVD burning program. I tried following some Google searches using regedit. I completely shut off my PC once done with registry then turn back on. I do a test using Nero burning music as data at 4x. It failed. What should I do?
