I can't burn any type of files onto a dvd for some reason...I tried burning a movie, an image, and even just a data disc. I have used Nero, Alcohol 120%, and DVD Decrypter. The media I have used is Sony, TDK, and Imation. I was burning fine and then everything quit working. The error I get is "Failed to Reserve Track! Reason: Cannot Write Media-Incompatible Format" Cd's burn fine in the drive, but DVD's do not. I thought it was the media's fault, but now I'm thinking I might have a hardware problem-any ideas? Thanks and Happy Holidays.
