I'm still struggling with this 5.1 DVD issue. It’s all a bit of a minefield for me. From the new 5.1 mix, currently I have burned one DVD with AC3 which it says is stereo although it came from a 5.1 AC3 file, a second DVD with a DTS track where the disc says it has 5 channels rather than an expected 6. I have also been given a DTS audio only Image File from the sound engineer that when I burn it says it only has one audio track. No video on that one so I'll have to run a separate video feed when I view it. I'll have to book a space to check this 5.1 mix - not sure what I'll find on these DVDs! Boy, this is tricky. Oh, by the way, when I try and create a m2v file from my original mov file in Toast it creates a very long file that doesn't match the original length and is huge when I bring it into Toast. I've ditched ~/Library/Preferences/Roxio Toast Prefs but can't find any plist. That didn't address this issue. Anything I am missing?
