I don't know what happened. 811 was finally working without major bugs with P284, but recently it's doing funny things. Don't have P285 yet. Sometimes when I turn on the 811 in the morning, DISH SD channels are exhibiting clearly visible vertical pixellation, vertical lines looking like saw tooth. I have to hard reboot to fix it. It does not happen on OTA channels or DISH high def channels, only in DISH SD channels. Also, certain OTA channels suddenly are giving me gray side bars instead of black side bars, EVEN in "normal" mode, not in "gray bar" mode. Mainly CBS OTA and channel 11 (KTLA in Los Angeles). Is this 811 issue or TV station issue?
