Recently I purchased a Onkyo TX-SR308 audio receiver and I need some advice about running my cable TV audio/video through it. Right now I have my cable TV running from the wall coax to the tuner on my LCD HDTV and then have the audio running from the TV to the receiver via the TV's digital coax. Ideally my audio receiver is supposed to work as an input switcher, with my TV remaining on one HDMI input, but with the way I have things wired, I have to change back and forth between the TV tuner and HDMI input on my TV. Does anyone know of a way that I can run the cable TV coax through a device that will output it to either HDMI, YPbPr, or composite that I can run into the receiver? The available audio inputs I have on my receiver are optical and coax digital, HDMI, and RCA stereo.
