Is there a slight chance you might mean you want to play VCD's?
A DVD (in the meaning of a 3,2 or larger beer coaster) is only readable with
a dvd player like H-man already said. But there are also VCDs These are CDs
with a (often) MPEG compressed movie in a special format. (A very loose
explanation, as I'm not so into movies) IIRC these cds can be palyed with
windows media player (Might be you need a specific Codex to play it, but I
know Media player can do this) As for the codex, I'm afraid I can't help you
with that one, but someone in thiss group might.
