Last night I had recorded the Presidential address from WNBC in NY. When I watched it later, about halfway through the address the sound became garbled. Syllables were being dropped. The DISH receiver (722) is plugged into an AV receiver. When the syllables were dropped, it appeared the AV receiver was trying to change formats away from Dolby Digital. I confirmed it was not a problem with the AV receiver, since I saw the same issue on the 2nd TV connected to this DISH receiver via the co-ax output. I tried recycling the receiver and it did not fix the problem. The problem continued on the next 2 shows I recorded from WNBC. I then went to live TV and had the same problem. This morning, the problem was gone. Did anyone else see a problem like this, or has anyone seen a problem like this in the past?
