Okay, so I am thinking about buying a blue ray player, but I was wondering if blue ray players also play regular dvds? or should I keep my dvd player when I get a blue ray player?
Yes Blu-Ray players most certainly play regular DVDs
It's called blu-ray because the disc is read by a blue laser, which allows
it to hold six times more storage than a DVD and because a blu-ray holds
a lot more memory it means the quality of the movie can be a lot higher.
A movie of this quality is too large to fit onto a normal DVD
