As a longterm TiVo user I'm struggling a little bit as the TVDrive is nowhere near as intelligent as the Tivo as a PVR. I'm no expert on TVDrive having only used it for a few days but it seems awkward in comparison with no search by title or wishlists and the remote has tiny FF/Play/Rewind buttons placed off-balance at the top instead of the central large arrow buttons on TiVo's remote. Recordings are scheduled via the 8-day EPG.
Nevertheless I'm slowly getting used to it..!
