Advertisements Any experiences with the Western Digital "My DVR" Expander Hard Drive? Are you satisfied or dissatisfied? Is this the only SATA hard drive that works with Tivo Series 3? I notice some other SATA drives (such as "My Book") which seem that same or similar but are available online at lower costs. Will they work with TiVo, too? Tivo Community Store does not show "My DVR" on its website. The only places I've found it are on TiVo's and Western Digital's websites (both a full retail). Does anybody else sell it?
