I'm not new at all to making backups. I have 50+ that work. But I just recently got a new DVD Burner. I've burned 2 games, and neither of them work on me or my friend's Lite-On 360's. Same discs that my old burner had no problems with (Singapore Verbatim's). What could be the problem? I know all the basics, burn a 2.0x-2.4x, etc.
