Hi everyone. I purchased a Sony STR-DG800 Receiver and connected a Denon LA-2300 Laserdisc player and a JVC DVD player. This receiver decodes 5 Dolby Digital and 4 DTS signals, but when I try to play a disc or dvd with DTS I get no sound! AND the dvd is in black & white. Regular discs & dvds play fine. The only thing I know for sure is that without the remote(getting one soon),I can't access certain settings. Could this simply be the problem, or something else? Also, the disc player has the AC-3 RF out but the receiver doesn't have the RF in. What can I get to make this work? Appreciate any help. Thank you.
