I am using DVD X Copy Express version 3.1 and after much struggle finally got it to both read and burn. The R+ disks play on the computer but not on any stand-alone DVD player. However, DVD RW disks play fine everywhere. I have a new Dell computer, plenty of memory and am using a new Memorex dual format burner.I have used 2 different types of R+disks (Phillips and Fuji)but get the same result.Any help will be much appreciated. Thanks.
