I have been having this issue with my 622. I'm running it on component outputs and not hdmi as the HD DVD player is on the hdmi port. This was happening on my last 622 also a few weeks before I sent it back. And now its happening on this one too. (Im really thinking its a software issue.) When the 622 does this it also makes a digital sound in the speakers.. its like a stutter.. I know it happens on WLS DT (abc chicago) alot, and I dont think that it has happened on other channels. I do get the digital stutter alot, (assuming that its also a software issue) for digital sound I'm using the optical port. The video deal that im seeing happens atleast once a night.. Sometimes it will last 2 seconds, there has been times where it lasted 30+ seconds (during greys anatomy season finalie) It was happening on the OTA tuner as well as the dish channel.. I have attached pics of what im seeing.. Are any of you seeing this as well and what's the email to dish quaility..
