Please forgive me if there is already a thread for this somewhere (the "search" button isn't working for some reason) but last week I bought (miss) understood / GUILTY CD+DVDs. It was too late when I remembered what happens if I tried to play the DVDs. (Yeah, I'm a smart one Dx) I don't know anything about technology, hehe

what sort of things can I buy (if possible) to be able to play my DVDs? Is it the manufacturer of the DVD player, or where I live that's causing the problems?
