Advertisements Houston Area Comcast users: Tivo rolled out the new HD channels in the 600 range today. Unfortunately, they removed the HD channels in the 200-300 range. The Comcast HD channels don't roll out for another week which means your Tivo will try to record shows in the 600 range (which are blank). All my old channels were removed and there is no guide data. Houston area Comcast users might want to unplug your HD Tivos from the network for the next week. ARRRGGGG. Call to Tivo Support yielded no results. It will take us a week to fix it. Idiots.
