Well... this one is long and involved... but I figure I'll post the info out there in case someone else has this situation. My dish was factory installed about 3 weeks ago.... one dish 500. I ordered my local NY channels. There were some channels avail to me that would come up and say "this channel requires another dish which Dish Network will supply for free"... so, why not... I scheduled the install. They came out last Friday and installed the other dish. Now there are two dishes on my roof. Just now I tried to use the channel guide (oh, by the way, I have a 522) and it only went out 2 days! I know I've gone out 6 and 7 days before... but now it wasn't working... I unplugged my 522 and let it re-acquire the sats and it said it was downloading the channel guide... took like 1 min for the channel guide... but still it only went out 2 days. I called Dish tech support.. they had me do a bunch of tests on the unit... and they concluded that when the 2nd dish was added, the guy must have knocked the other dish out slightly... he said they would send someone out on Wed (today is Monday night) to fix the problem... which I thought was ok. Then he said he put in for an "interruption of service" credit for me for the inconvenience... $10... but I thought it was a nice guesture. Anywho.... just thought I'd pass the info on.
