I am having an issue where I can't find certain shows when I do a Search by Title on my HD Tivo. However, the show appears in the Guide for that TiVo. Curiously, the show is also missing when I do a Find TV Shows on TiVo.com for that box. The show DOES show up on my other TiVo, in each of Guide, Search by Title, and TiVo.com Any help would be appreciated. Note that I tried reconnecting to TiVo through network settings, to no avail. Do I need to repeat guided setup?
