Very good to know. Next question:
Gladiator is recorded in DTS ES. My Sony DVD player decodes DTS but makes no mention of DTS ES. I wonder if it will send the 5.1 channels of regular DTS or if I'll have to switch and get the matrixed center from Dolby Digital?

I haven't received my surround speakers yet so I haven't had a chance to play around with it yet. I appreciate the input and have found the saloon very helpful and informational.
