I recently purchased a DVR-810 on which the previous owner had a an expanded Tivo service. When he sold it to me he cancelled the service. Now when I try to connect to Tivo all I get instead of the basic channels display is a showcase display. When I go to the DVR system information the display indicates that service is cancelled. At both Pioneer's and Tivo's service departments request I have cleared the entire unit without success in reintalling the Basic channel service. The Showcase is worhtless. Does anyone out there have any advice as to what to do? All other functions on the unit are working fine. Thanks!
