I loaded up Gladiator the other night and selected the DTS ES option for sound. The movie started and there was no sound coming out. I guess I should explain what I have now so that maybe you can tell me what is causing this or fill me in on what I don't know. I have a Yamaha HTR-5790 (7.1) receiver currently set up in a 5.1 configuration until I get my speakers. My Toshiba DVD player is hooked to the receiver via digital audio cable. Are there some settings that I need to change or will my setup not push this source?
