I have recently noticed that the audio synch on the OTA HD broadcast is really bad when viewed from the DVR. Do anyone else have this problem and is there a solution? I have checked the synch settings on the 622 and I believe they are set correctly. I have an optical link from the 622 to my Denon 3803 and an HDMI to DVI cable from the 622 to my Mits 55" TV.
