OK. I hesitate to post this because it sounds so strange.
I have noticed recently on my HR20 (connected to Philips LCD panel) that occasionally I get a narrow white line flash on the screen that's about 6" long and is positioned toward the upper right side of the screen. I have a bar fridge not far from the system and just figured it might be the compressor kicking on/off. No big deal.
Now, I'm not so sure. I have an HR21 (connected to a Samsung DLP) downstairs in the media room and I have started noticing it there too. It is very infrequent and lightening quick. In fact, my wife hasn't seen it (at least hasn't complained).
The two receivers are on different dishes (ruling out dish and multiswitch - only one has a MS). I have only noticed on HD as I seldom watch SD sources. This has only started in the last couple of weeks and there have been no changes in my electrical system.
The only thing I can think of is some problem at the panel with the house power/ground. The circuits are a long way from one another and, of course, on separate breakers.
