Will my DVDs become obsolete?

Episode 1197 (1:53:33)

Paul from La Jolla, CA

Paul wants to know if DVDs are going to be obsolete. Leo says not really. As long as his DVD player works, it will play. Eventually, when the technology changes, DVD players won't be available. But Blu-ray players can also play DVDs, and Leo has a hunch that backwards compatibility will continue.
