Yes, I picked it up myself. Everything else is working fine, ON DEMAND included.
I called again, the CSR I talked to said I was correct, this is not normal. So she sent a tech. I showed him a few of the TO BE ANNOUNCED listings, taking place within in the next couple of days, one for THAT day. He checked the signal coming into the unit, and the signal as it came from the street to the side of the buildings. He said that the signal was fine, and that it was not abnormal for that to happen, they had been having some "problems" in the area, but didn't go into detail about what those problems were. He said that many experience the same situation. He seemed to know what he was doing, so I don't doubt him. He did say that Comcast/Moto is years behind in Guide upgrades, and said they were working on some kind of box that would store the guide and all recording "in the clouds." I have a TiVO in another location for more than 12 years, and it has NEVER lost the guide. It's obviously something that I must live with, unless I get a TiVO.
