I have already replaced more than 10 percent of my 2500+ DVD already, and still going strong. I intend on replacing every DVD that is released on bluray in the future.

When it comes to my hobby, I do not worry much about how much things cost, or how much money I lose when I sell something. I like having a library of movies, so I never rent, I buy. Bluray and HD DVD have finally made my expensive investment in equipment worthwhile, and I am going to milk it for all its worth.
