I do the same at the pawn shops Mixx. We're running out of good DVDs to choose from. I gave away tons of my DVDs because I tire of stuff like teen romps and college antic movies.
I like Crime, Drama, SciFi, Westerns and True story as well as some Comedy. I have tons of favorites that never got shown on TV (in my local area but maybe on cable). My collection is worthwhile and I have some that will never get shown on TV due to subject matters.
So far I have 872 DVDs cataloged but I have more like TV shows, Stand-up Comedies and whatever that I don't bother to log.
