Hello. You can customize your list of channels that you see when you're channel surfing and using the guide here: Messages & Settings->Settings->Channels->Channel List I have unchecked all the channels I do not receive (PPV, etc.). Several times now when I go to channel surf I notice that these channels that I removed are showing up. When I check the above menu settings, the channels I unchecked so that I would not see them are magically checked again. I'm not talking about Favorites, just what channels I check/uncheck depending on if I receive them or not. I am using System Software 8.3.1 on a Tivo Series 3. Any way to get this to stop? It's getting tedious having to uncheck all the channels every so often (doesn't happen every day). The TiVo upgraded itself recently, so I suspect that it had something to do with it, but it's happened now more than once.
