I've never seen Tivo get something as a Wish List item unless it specifically matched the programming of one of my wish lists.

I *have* seen Tivo grab shows that I didn't *think* matched a wish list, until I looked much closer.

I suggest carefully re-evaluating any wish lists you've programmed and seeing if some kind of search is coming up as a match. Something subtle that you're not noticing at first.

By the way, press the details/info/whateveritscalled button when you're in a show description screen to get more details on the show, such as original air date and its genre match types.
