Most DVD players don't need any special driver to operate. there is a driver, included in the Windows installation, at it works fine. So IMHO you need just to repair your windows with the windows install disk.

It's a common problem in Win 7, usually down to a corrupt registry key.

Follow this article if your happy editing the registry, should have you sorted in around 5-10min.
