Hi, I've recently started having problems burning movies/data to DVDs. No matter what program I use whether its data/video via Nero (7 Premium) or movies using DVD Decrypter, DVD Shrink or CopyToDVD (movies using last 3) the computer goes through the motions of burning but at random times the disc sometimes won't recognise on my PC, sometimes it does. The tooltip for my burner says "Used 0, Free 0" Sometimes these discs that aren't recognised in my PC will play in my DVD recorder (LG DR175) and sometimes they won't. My burner is an NEC ND-3550A My burner is newish and has only burnt about 50-80 discs in total since I bought it from new. Could this be a problem with my burner? Maybe firmware? The latest firmware is 1.06 (that I can find) and I have 1.05 installed. All these problems started happening since I upgraded to Nero 7 Premium and I don't want to have to go back to a previous version of Nero if I can help it (if Nero is the cause of the problem) as that would be a waste of money upgrading Nero although I will if I have to. Many thanks. EDIT: At the end of every burn it says the burn was successful.
