I lost channels on both my Thompson in the den, and my HDTivo. Channels were unchecked in my Favs on the Tivo. Checked them again, everything was fine. Rebooted the Thompson, and Fittv was missing from the channel list. Punched the channel # fitTv came up, scrolled thru channels, and FitTv was still there but it was still missing from the channel list. Checked tonight and its back on the channel list. Thats weird.
