Copywrited DVD Movies require that an MPEG software DVD Decoder be installed on your system. Windows doesn't include any because of their Anti-Trust violations and court issues.
(not to be confused with other media players, and DVD players that are included with DVD Movies, such as HOTLLAMA, and Interactive - you still need a DECODER. This is a throwback to the early days of PC DVD ROM's that required a HARDWARE MPEG DVD DECODER be installed, usually in a PCI slot, and connected to your video card through the VESA expansion connector. Nowadays, the hardware is built into the DVD unit, but it still requires a software decoder to operate).

Every DVD ROM or Burner comes with one...usually "Cyberlink PowerDVD", and now Nero's included one in their bundled OEM package.
Any version of any one of these will unlock the "DVD Movie" features for all media player installed on your PC.
[oops, almost forgot, you need Nero 7 or better for Vista. Any Cyberlink should work for you].

If you don't have one, try borrowing one from anyone who's got one. You can also go the P2P route, and download one, if you're so inclined.
Good luck, and I hope that fixes your problem!

You need a piece of software to play DVD movies. Is this an actual DVD movie, or is it an MP4 or WMV/WMA file?

Usually you need something like WinDVD to play a DVD movie. I don't think Media Player can play those.

Did you recently install another piece of software that might have affected your ability to play DVDs?

you need powerdvd or windvd which has the decoder for dvd. can it read regular data cd's ? like install a program?
