i have about 3000 regular dvds that i dn't watch anymore because about two years ago i switched to blu, the difference between blu and regular dvd is strking, if you are honest. almost three times the video resolution, sound can be what they call lossless, that can't happen on a dvd. plus there is much more room for extras on one disc compared to all those multi disc dvds that you have to swap out to see everything. i would convert if you can afford it, your old dvds are becoming more and more worthless as time goes by.
