I just upgraded from Roxio 2010 (worked great, not sure why I upgraded) to NXT Pro 2. I have tried to burn 4 Data DVDs and the process appears to work great. All the files are copied and the disc (DVD+R) is written to. But the disc is unreadable on any of my computers. I have even tried to "finalize" the disc (which I never had to do with Roxio 2010) but the Roxio doesn't even recognize the disc it just burned. Any suggestions?
