+1 for a Direct to Video category, which imdb also has - simply as "V".

I'm not sure about subdividing TV in too many categories. Why Non-Fiction TV when there's a documentary category? Top Gear is fine as "TV-Series" IMO, and talk shows and reality are not allowed anyway.

http://www.imdb.com/title/tt2227372/ is listed as "TV" which is perfectly sufficient. You could just change "TV Show" to "TV".
