I have had a problem with two Windows XP computers. When I put a DVD it does not play, however CDs do play. I solved it my running the five step error checking on Windows (3 step did not work).
Obviously a problem I caused but I am just wondering if anyone can give me insight on what I might have done (on both computers) and what Windows did to fix it. Would like to know so I do not do it again.
Many thanks!
