If you ave enough video inputs on your receiver, IE: VCR, TV, SAT, DVD etc, plug each system in to a different input. Then plug the video out (or monitor out) in to the TV, DONE! Use the TV only for the picture, rout the video and sound through the receiver and use it to switch between all the inputs. That's why you have all those plugs in the back.
k so heres my proble. i have a rca home theatre system, an RCA 32 inch xbox ready tv, and all the major video game systems (xbox, gamecube, ps2, n64). i was wondering how i could go about hooking them all up to my receiver for surround sound. right now, i have the three colored wire running from my digital cable box to the back of my recevier where it says "TV". that gives me the surround sound on the cable channels. how could i hook up all my video games so they all play thru it. i dont have the instruction manual either. but theres plenty of input jacks (red, white, yellow) on my tv. just wonderin how i could set it all up
