I just got my first BSoD in a long time by watching 30+ minutes of local DTV, then surfing to a satellite channel.
Also, while I was watching my OTA DTV stations, I noticed my Midnight timer didn't fire at midnight, even though the clock was 12:02 am. I did an Info and the 811 had the right channel info, but maybe the 811 can't get there.
Now I have a GSoD! I popped up the guide, still no video, and when I cancelled back to channel 9900, it was all grey, no audio. I hit the "Sys Info" on my remote, and it appears there is no JPEG image behind the Info Screen: it's black, with a green "GOOD" (hah!), a blue "0", the phone icon on a green background, a blue "P287", the switch matrix in white with my three satellite positions (119, 110, and 61.5) in black with green boxes underneath, "SW21 3-SAT" in blue under that, and a blue "1" (my remote address, I believe). Looking closer, it appears the text is a very dark grey on the black background.
I tried my "Dish Home" trick, and the audio comes up in the background, but no graphics backgrounds. The Instant Weather app works (again, no background or ads, just the text characters.) Cancelling out, I can pull up the music channels (both Muszak and Sirius) with audio, and after the banner goes away, the song title, artist, album, and publisher info appears. Again, text graphics, not anything coming out of the MPEG/JPEG decoder.
One big difference between P287 and previous versions: When you get the BSOD, you lose the Menu graphics now. Before, with the "primative" menu buttons, you had a complete screen. Now, all you get are white characters on a black background.
