Just got my 622 today and having audio problems. I use optical SPDIF and have no problems when watching "live". Using the DVR the audio will drop out about every 15 seconds to 2 minutes for about 5 seconds. It is not a recorded dropout because I can replay and the audio will play fine for that spot. During the dropouts the 622 continues to send a (blank) DD signal but with no sound. It looks like I'm not getting off to a good start with E*. What are my options?
