Chess, if you have an oppo you may be able to use the multichannel analog outputs into your avr. You can then use the oppo for HD audio decoding and your avr will basically become just an amplifier.

You didnt mention which oppo you purchased, but if it is the 103 or higher, it has channel controls like distance and spl trim level built in. It may afford you more features than your onkyo currently offers in terms of system setup parameters. Not sure about the 83 or 93 though.

You can also use the HDMI out at the same time for video only. This means when your tv is replaced, you can bypass your avr for video and go straight to the tv from the oppo. The newer oppos also have video inputs for hdmi and can act as a switcher and scaler. I believe they will also strip the audio from inputs and output over analog to your amp as well.

Good ole oppo! smile
