The blu-ray players today take ordinary dvds and make them better - not as good as real bluray but better than a standard dvd player would. Talon’s the one to ask if you want a detailed explanation but basically, the colors look better, the edges are sharper, it’s a nice thing.
That’s probably about as much of an explanation as I’d understand. ;-)
Cool!
If I ever stop spending money on writing stuff and music things and bike stuff and cars...someday it’d be nice to have a better TV and DVD player. Maybe once I have my own place.
