I was experiencing a similar issue. I decided to check to see if the Logitech Review I have on that TV was having any impact so I unplugged the revue from the HDMI chain and had no issue for a week. So I plugged it back in and had the same problem within 2 days. So next I took the cheap HDMI Cable that came with the Revue and swapped it for a higher quality HDMI cable I had. So far no issues.
My suggestion is to by pass the Reciver for a couple of days (I Know no sorround sound that way, that will suck) and see if that clears up the issue. If it does try replacing one or more of the HDMI cables in your setup.
