Are the two types of disc so different that they actually need their own classifications these days?

The difference between Blu-ray and DVD is like the difference between ham radio and CB radio...

Both are digital disc formats, but DVD is plain old standard-definition MPEG-2 video. Blu-ray is very high quality high-definition video and usually lossless multichannel audio (on most discs these days), along with optional multifunction special features far beyond what DVDs ever offered. No, Blu-ray discs will not play in DVD players, any more than LP records will play in a wind-up Victrola. (DVDs will play in Blu-ray players, though, and they will probably look better than in most regular DVD-only players as well.)
