I had a strange experience Wednesday evening, April 25th, about 8:00 P.M. PDT. I live in Anaheim, CA. While watching a recorded program on my dvr, I first got an audio interruption, starting with a series of sharp, "electronic" beeps, then the picture froze, and the voice part of the program began to stutter, and repeat over itself, while sounding like something coming through a synthesizer. I tried backing up and repeating, but no luck. I also tried live TV, with the same effect. I also noted that the receiver was very sluggish in responding to commands from my remote. I have a 722K in the living room, which is where the problem was (I also have a second 722K in another room, which was working fine on DVR and live programming at the same time). I did disconnect the power from the subject receiver and restarted it, but no effect on the problem. This morning, I was going to contact DISH by phone, so I checked the status, it is running perfectly, both with the same recorded program I had the problem with, and live TV. There were thunderstorms in the general area, but I assume that would have affected the other 722K as well. Does this sound like something that might be affected by solar activity? Would appreciate any input. Thanks.
