Anyone out there installing 722's?..I had an install on Sat 8/25..oth 722's had issues. One had no audio..Tried it using composite audio. The connected the supplied hdmi to DVI cable..Note, the Plasma Tv looked like an older Hitachi, did not have an HDMI input. DVI only..I figured it was a software issue so I downloaded and activated...Still no audio..Swapped the HDMI/DVI cable. No go..Shortly after activation, the video failed...Swapped receivers...Second 722 no audio...Anyone experiencing these or any other issues?
