It really seems like it wouldn't cost that much to have some type of movies or tv shows available. Especially when the screens are already in place...
As I said, If I recall correctly on the 752's the screens maybe there but the systems to operate them have been removed.
Also I agree I don't care much for IFE, usually the selections shown for the main cabin isn't great to begin with, i'd prefer to read a magazine or go over some paperwork than watch Herbie.
