I'm not only buying Blue Ray for the HD by the way.
I have found out over the last year that the huge majority of Blue Ray have a french soundtrack whereas this is not so often the case for DVD( especially Disney which pretty much doesn't support french on its Blockbusters on DVD anymore ).
This is very usefull for me as I need movies to watch in french when my parents come to visit me in the US :P ( yes I am french and live in the US).
Ratatouille and Pirates of the Caraibs 3 DVDs had no french, the BlueRay did.....
