I just got around to watching some shows on my DRT800 S2/dvd unit and the last few shows didnt record and I got a message that they were not recorded because it was scheduled with a "Tivo Plus" feature. What is tivo plus? I thought that was the old term for paid service not the free basic service that came with Pioneer/Toshiba DVD units? My unit has full paid lifetime service for the last 6-7 years. Any ideas?
