I'm having a strange problem, and I guess it's probably related to this. Yesterday around 6 pm, all my channels went dark and I got the 721 message. I called in, and they said they were switching over us former Pegasus accounts to a new system. Everything came back on. Then, about 2 am last night, I lost some channels. I'm getting a 721 on all of my HD channels except SHOHD, HBOHD, and my distant ABCHD and CBSHD. Is this related to this stuff? Will they mail me a card, or does it have to be UPS/FedEX?
