TiVo doesn't offer any type of management for the Now Playing list. Therefore, any recording that I didn't ask for is adding clutter and confusion when trying to browse the already growing list. Plus I didn't have the patience to delete recordings for a couple of weeks or months before I stopped picking up crap. Even then, a lot of the stuff I watch might make it go out and record a bunch of other stuff I really don't like. I've had a look at the Tribune data they use (and documentation) and I'm pretty sure what the basis is for their suggestions.
