I have looked at the web sites for dolby digital and dts and got there lists of movies that are in 6.1. Dolby has a long list of DVDs that are in dolby digital es which they say is 6.1 but most of them that I have checked are not. The list DTS gives seems more acurate but some are not. Here are the DVDs that I have found so far that are in true 6.1. Terminator 2 the ultimate edition, both lord of the ring dvds, Pirates of the caribbean, Finding nemo, Harry potter and the chamber of secrets, Gladitor, and Blade II. Does anyone else have DVDs that can be added to this list. Thanks for your help Cope
