Hi all, Just wondering if anyone can help me out here. Just tried to back-up Blade & Blade II but got the same problem with both of them. Basically, I had to split them over two discs each. First part is always OK but the second part has an AC3 file which DVD Studio Pro doesn't recognise, why is this? Software I'm using: DVD EXTRACTOR 0.9B DVD STUDIO PRO 1.5 Hardware: APPLE MAC G4 System Software: MAC OS 9.2.2 Any help, mucho appreciated!!
