I have a Pioneer A03. I have several types of software for burning and authoring, Spruce, MyDVD, Nero, etc. No matter what type of file I burn, Data or video, I acn't get the disc to recognize in any other unit, including a second DVD drive in my computer. Can anyone offer any advice. Ultimately what I am looking to do, if it is possible, is to make audio only discs, but I can't get there unless I can get ANY file or disc to be recognized at least in my second drive. Thanx a million.
