Video content already price discriminates similar to how Valve uses sales to sell games.

At release: Movies are 12 bucks a person a view at the theatre. Games cost 60 bucks.

After a while: You can rent a movie for 4 bucks or buy it for 15 bucks on DVD. Games cost 30 bucks.

Year + later: It's on HBO, cable, network TV or netflix. Games cost 5-10 bucks ON SALE!

Maybe movies could be sold for super cheap after a year, but for the most part there isn't much interest in the movie.
