I'm having alot of problems with this thing. I'm trying to follow the instructions but there confusing me even more. First off I cant get the auto speaker setup to run. I go to the auto setup screen and try to hit start but nothing happens. I'm hitting the left cursor. that does not work. Next is sound. I can get sound using red and white coax but if i hook up optical i get no sound. I'm using a sony cd changer plugged in the v-aux front panel input. I set the digital input to opt 5. still no sound. Also when using the L/R coax I only get L, R and Sub when i hit any other 7.1 sound setting I loose the sound. Im really lost with this thing. I have no tv hooked up to it so im trying to follow the little screen.
