Yesterday, after the Pats-Colts game, my 811 started messing up too. I would get black bars on the screen (horizontal) and the color would fluctuate. I've never experienced this before. I changed resolution to 720p and the picture was fine. I was using my DVI, so I hooked up component and the same thing happened. I called Tech support, got forwarded to Advanced Tech. I told her everything that I did, (Including Re-Boot) and she said the box was bad. Told me that it was out of warranty, but since i'm a long term subscriber (Since 97'), I could pay $22.00 for a replacement box. $15.00 shipping charged waived w/ CCAP. I do disagree with ALOT that dish does, but this was nice. Showed me that they care a little about a valued customer. Anyway, I can't say if it was a software issue, but everything was fine before p284. Also, if I switch between zoom, partial zoom, grey bar settings, the grey bar setting makes the whole picture darker. Never done that before either.
