I have two 622's. Experiencing the same issue on both of them.
What's happening is that I'm getting periods of a blank screen when playing on demand shows. It will go blank for about 2 seconds then come back on. This happens at least a dozen times during a 50 minute show. Maybe more often. Again, on both devices. Audio stays on without issue.
One 622 is connected directly to my router, the other is connected through a switch to the router. Most of the time I do the on demand request ahead of time and watch it later after it's fully downloaded.
Tried rebooting the devices. Still the same issue.
