ok. i downloaded, yes, downloaded so don't bother yelling at me since i don't care...a THX Demo DVD...now i can run it in either Dolby Digital, or DTS...i'm guessing they are both about the same? it seems DTS sounds a little better, clearer, and brighter, but DD sounds great too. are most movies made with both on them now? also, if you can find dvd, i highly recommend it...wow. it really shows you what your equipment can do!!! just wondered if there were any thoughts,....other than shame shame for downloading etc....get over it...the horse is outta the gate on that one...no going back now.
