I just installed a new out of the box PVR-501 with the platinum remote. During the dish aiming, the audio and remote worked fine....I even watched the international chanel 580 for a while with no problems. I called in the Sky Angel activation, waited a few days, then turned the system back on. It downloaded an update, then started showing the SA programming on the second day. The only problem is that now there is no audio (on coaxial, RCA or digital outputs) and the remote stopped working. I reset the system and have tried resetting the remote channel, but nothing seems to help. Anybody know what else to try?
