I hooked up my cousin's surround setup today. Sony 46" HDTV Yamaha RX-V730 Sony DVD/VCR Combo Cable box Polk RTI's all the way around I can't get any video stuff going at all. I have monitor out from the receiver to the comp video in on the TV. Then I had the coaxial cable for digital cable out of the wall into the cable box. And component cable out of the box into the reciever. I also have the DVD hooked up via component cables. I went into the Yammie menu and set all the I/o's to what they should be and I get audio for both the cable box and DVD player (optical and coaxial respectively), but no video what so ever. Surely all three comp video ins/outs aren't dead on the Yammie? The thing was just bought new last week.
