This has happened a couple of times now. Showtime-HD (9430) is in the guide (I subscribe to it) and then it's gone after a number of hours. We're not talking about it showing up as red but gone completly from the all channels and subscribed guides. If I do a reset on the 811 it will come back but then again in a few hours it's gone again. Anyone else see behavior like this on 9430 or anyother channels??? Thanks - Rick
