When Blu-ray was coming out, there were to be "Blu-ray only", but someone said, "What would it take to get them to play a DVD?"
"Add a red laser to scan. But that will cost more."
"So?"
So Blu-ray players can do both...as if they didn't they might be slightly cheaper...but no one would have bought them....as backward compatability is still important. just look at all the VCR/DVD players out there.
