Sigh, this one's got me vexed.
Tivo Premiere DVR, totally empty of any programs (no suggested, no recordings, no nothing). Wishlist items programmed, set to record, no conflicts, delete when space needed, save up to 5 episodes. The show comes on, the Tivo records it, then immediately deletes it (even gone from recently deleted) and reason listed in History is "space needed". There's nothing recorded, please help!
