I'm not trying to start an argument on DTS-ES vs. DD-EX... I got the Terminator2: Ultimate Edition DVD and it has BOTH a DTS-ES Matrix 6.1 mix AND a Dolby Digital-EX 6.1 mix.... Which one is better? The only other Discs I have that do the 6th channel are Episode one, and Gadiator. In both of those cases, it's obvious which format to choose because the other doesn't do the 6th channel. But on this DVD I have the option to do either. Does anyone know which mix is better on THIS DVD?
