My TV is plugged into Video 1, DVD into DVD, etc. but whatever channel I turn it to that has some type of video associated with it, I get TV sound from that channel. DVD, Video 2 and 3 TV/Sat, I get the sound from my TV, and not what I selected. CD, Phono, and tape all work fine. it is just the video channels. I have tried to plug my DVD player into the video 2,3 and tv/sat channels and that does not work. plugging the DVD audio into the CD channel I do get sound. If you have any ideas please help.
