I know for a fact that a lot of people do.
Personally, I can't speak for gaming, because I don't pirate games, but I do pirate a lot of TV Shows and movies ... And when I see something I like, I always buy it on DVD. I own Seinfeld, How I Met Your Mother, The Big Bang Theory, Psych, House M.D., Heroes (first two seasons only), Lost, Arrested Development, It's Always Sunny in Philadelphia and probably a few more I'm forgetting on DVD - and I started off pirating every single one of them.
As for movies, I'm not even going to go there, because I've bought well over 50 that I started off downloading...
