Well since the update I have to reset the receiver twice a day. I get frequent audio drops, just for a micro second, but noticeable. I also loose audio on HD channels, but if I hit the skip back button it comes back, but when I go back to live TV, it's gone again. I also get picture stutter on all channels, even on OTA's. I am running the 622 in single mode, using component and optical to my AV receiver.
