I've just successfully burned my first DVD backup after browsing the threads and finding ScubaPete's excellent idiot's guide to burning with Shrink and Decrypter. Before finding this my first effort produced a coaster! I selected AC3 audio only, after reading another guide, but have noticed that the audio quality when played on my JVC standalone player is inferior to the original. This is a music DVD so this is a factor. I don't mind sacrificing some picture quality to improve audio quality in this particular case. Obviously LPCM audio must be of a better quality (it certainly takes up far more space); is there any way of telling which audio channel my standalone player is reading on the original dvd, AC3 LPCM or DTS? Or must I experiment to see which produces the best results for me? Unfortunately my standalone does not appear to read re-writables. Sorry if this is maybe going over old ground but I'm very much a newbie at this.
