Hi all -
I've been following this forum for a while, and I'm now in a position to request advice.
I have a Tivo HD with twin Comcast Cable Cards; everything is about two years old. Over the past few months, seemingly at random (and mostly in the evening), I'll notice total (zero signal strength) dropouts of only selected HD channels (always in the "network" channel range -- CBS, NBC, Fox, ABC, PBS). All other HD and non-HD channels remain fine. Sometimes the problem disappears in a few hours, sometimes by the following day. I've had Comcast techs here on 4 occassions (always a day or two after the problem has occurred and disappeared) and they can find nothing wrong with my setup or the connection from the street.
Last week, the problem occurred again, but with a VERY odd "extra". The select channels (cable 802-812, but not 808 [QVC]) went black at 6PM on the dot. A few reappeared at 8PM, then they were gone at 9PM. At 11PM, everything was OK, with NO outage on any channel. This does not seem random to me, given the changes occurring at the top of each hour.
I again called Comcast to see if someone in outside plant was making changes or performing maintenance, but of course nobody could say if this was the case, and didn't believe that was the problem. Comcast admits that this is very strange, but all they want to do is keep sending techs to my house, just to find nothing wrong. They're coming again this Friday.
Does ANY of this sound familiar to anyone on this forum? Could it be something wrong in the Tivo HD? Cable cards? I've tried resetting the Tivo, but nothing changes. Any suggestions? This has become more than frustrating, as I end up recording black screens when it occurs.
Any advice would be greatly appreciated.
