I cancelled it about 18 months ago and they didn't ask for anything back. The dish sat on our roof. Cable gave us a better cost and I'd @*$#ing had it with the storms knocking our service out, too.
I had no problems with Dish except their HD box would NEVER update the program guide. We'd have to reboot, wait5-8 minutes just to get the program guide EVERY DAY
We didn't have HD but experienced the same thing very often, sometimes inexplicably, like I'd already been watching tv and had to wait at least a minute for it to DL the guide. DROVE ME BAT CRAZY. The bandwidth of the dish is obviously high to handle video but it takes a year to download a few k of program guide. It was admittedly a continual and major annoyance.
That would be due to a problem with the phone line quality on the dialup line it was using. Same deal has dialing into the Internet on a crappy phone connection. Do you have DSL? Some people forget to put a filter on that phone line too.
Well, like I said, we didn't have HD so it wasn't the same thing, but we never had our dish connected to a phone line ever--the regular program guide took a long time.
Of course now that we have cable, the guide is always loaded but SERIOUSLY slow, which drives me nuts in another way. At least once dish was downloaded its menu was snappy.
