Thanks very very much bro!!!:) I'm thinking about using PowerDVD XP, but what's the publisher's homepage for daemon tools. And also I selected my dual layer project to be Opposite and how do I set the layer break? When I go to track setting is Simulation editor.And "set layer break" is greyed out? but in the 2 choices: Parallel or Opposite, Opposite is selected and is also greyed out. So how do I set the layer break? I apreciate your help!!! Thanks In Advance!:)
