I have a 622 receiver that is set up to record a number of shows. Watched DVR'd Idol from 2/12/08 - no problems. When to watch DVR'd Idol from 2/13/08 and I have no audio for Americal Idol! The strange thing is that ALL comercials have sound it is just Idol that doesn't have audio. Is there anything I can try to get the sound to work? I have reset the 622 and that did not work.
