I have had my Tivo Premiere since 9-12-2011. I haven't had any problems with it until Friday, 9-30-2011. I was watching the Texas Rangers playoff game and it decided to restart on its on. The next day the Tivo lost all the cable channels. I tried several of the channels and the unscrambled channels screen said it couldn't find a signal. The scrambled channels said channel not authorized. I restarted the Tivo from the Help menu item and the channels reappeared. The cablecard is a Motorola cablecard. Last night Monday, 10-3-2011 we were watching some recorded shows and when we finished watching, all the cable channels had disappeared again. I tried to call Tivo, but it was after 7 pm PST. So I started a chat session. Before I called I restarted the Tivo and all channels came back. They guy had me look at some diagnostics and thought it might have been because of a signal dip. I called Tivo support this morning and the tech echoed the same thinking about a signal dip causing the restart on Friday and losing the channels on both occasions. I expressed that the software seemed to be less than robust if it couldn't recover from a signal dip. We agreed that I would monitor and not restart the next time the loss of channels happens during support hours. The tech also mentioned that a new version of the software was being pushed out toward the end of October. Has anyone experienced these problems before?
