I just purchased and setup an Onkyo TX-8222 stereo receiver that I was hoping to use with my TV/HR20. Unfortunately, none of the Onkyo Stereo remote codes seem to allow me to control the volume with the HR20 remote. Has anybody out there gotten this combination to work? I've tried the RC24, RC32, and RC64R remotes - each with all 5 Onkyo codes, no luck. Any ideas?
