I was able to hook up my cd and minidisc combo player but when I try to hook up my dvd vcr combo to the dvd/ld hookup nothing comes out. I tried the vcr/dvr hookup and it works but only in analog, not digital even though the dvds I try to play are dolby digital. I also am unable to hook up my Toshiba tv to the receiver. No sound from any hookups. ex: tv/sat, etc. I tried the audio out on my tv but no luck. Any help would be greatly appreciated. Thanks
