I've been having an issue the last week or so with video jitter on my 622. It did it last Friday through the whole episode of Friday Night Lights which I had DVR'd. And I really hadn't noticed anymore until yesterday. There were several times throughout the day and then during the Tennessee/Memphis basketball game it really got bad. Then later on into the game, I swapped tuners and turned to the same channel and there was no jitter. So is this an issue with one of my tuners? I did notice later into the night that the jitter was gone with either tuner. I wonder if this means my 622 is slowly kicking the bucket?
