As the title implies, I'm having trouble with DTS mode producig any sound. I have a dts capable dvd player(panasonic dvd-a120), and reciever (Yamaha rx-v620), as well as Gladiator, that has a dts soundtrack. I set the reciever into dts mode, put the movie into dts mode, connected them with optical cables, and...no sound. I also tried coax digital, as well as regular analog audio with no sound either. When the dvd player is set to optical, it recognises a PCM signal, but that's it. I'm stumped, why can't i hear DTS?
