I've been having a really annoying issue with my 622. When watching some recorded shows, the audio will start stuttering and it fixes it to hit pause or skip back. Sometimes it is really bad and does it often while other times it doesn't do it at all. Strangely it does it everytime that I record People's Court on NYC local on Conus. It did it tonight when watching American Idol recorded from NYC FOX on Conus. I haven't noticed it on shows recorded from other channels and it doesn't happen when watching live TV. What could be causing this weird behavior?
