For your consideration:
Could the "On Later" screen have a way of bypassing all the fine tuning and just present all unique shows Channels knows about without breaking them into genres? Maybe sorted alphabetically?
The division between "TV Shows", "Movies", "Sports", "Kids" is still nice.
But within those categories, I find it isn't easy to pin shows I'm interested in to a specific genre. Say I like crime shows. Sometimes those fall under "Crime", sometimes "Crime drama", sometimes "Action" or "Mystery" or "Thriller" or "Drama" or "Law" ... you get the picture. And they all have slightly different lists of shows in them.
I don't want to miss something I'm interested in because I had filtered the genre/channel. So I went through and selected every channel and every genre available. Now, while I get everything, there are some shows listed many times in the "On Later" section making it cumbersome to browse.
In my case, it would be more efficient to have a screen that essentially just does a "SELECT DISTINCT show FROM guide WHERE date > GETDATE() AND type = 'TV Show' ORDER BY title ASC" (or Movie, etc.) and presents the result.
