In response to lithnights, Corect you don't have to use you TV remote if all audio is coming from your receiver and speakers, I don't know what receiver do you have but with the new receivers today you can program the remote of your receiver to do the "previous channel" (I'm controling the DVD,DVR, TV, with my receiver remote.)
to be sincere I Myself do not use the receiver as the center I'm running all the cabels individually direct to the tv, it is more work and money but I believe it give better Quality because of- "the long you go will give you more amount of resistance inbetween this equal less quality" some agree and some not. but I believe most a/v folks do leave their TV on Video 1 and just control the channels (cable, satelliite etc.) via their DVR, VCR, it is easy less work & inexpensive.
