We have started getting a black screen on our HR-44 Genie when we fast forward. It happens in the last few seconds of the FF. We can then let the FF continue until the picture comes back. At that point we can back it up to recover everything that happened during the black screen. This doesn't happen on every FF. Maybe 20% of the time.
We also get a short black screen of maybe 1/2 second ever once in a while, as well as some occasional pixelization. It's the black screen on FF that is the most annoying.
