Thanks LONSat for the reply. My signal levels are fine, around 90 + or -, where they have always been. It froze up again this afternoon while I was just watching live. Did a front panel reset, it got stuck on "hold". Did a disconnect reset, same thing. Then disconnected everything and restarted with the external HD still disconnected (this is what I had to do right after the download) which finally brought it back to life. I deleted a manual recurring timer which seemed to be giving it trouble plus all other recurring timers and connected the EHD and did a front panel reset. It now seems to be working fine but I think I may need to do a factory reset some time.
One would think that the first thing the CSR would recognize when it wouldn't tune to ch 350 is that it was on the advanced lineup, but I guess she was so anxious to stop the criminals with receivers "outside the service area" that the obvious did not occur to her.
