I just bought a sony dru700A dvd burner from the sony website. It came today so I tried to burn a dvd with it. I am using imation 4x dvd+r media. The dvd will play in my burner, but not in my tabletop dvd player, sony playstation 2, or computer dvd player. Does anyone have any info to help me. Also how do I figure out what firmware I am running and where can I update it. Thanks for any info.
