problem watching the wmv files

Hello, I'm trying to view files with a wmv extension, I get the following error message when I do so. thanks for the help

n order to play this file, you need to upgrade your media player to a version compatible with Windows Media Rights Manager V7. Select View Compatible Players below to see a list of compatible media players.

If your current media player does not have a Windows Media Rights Manager V7 compatible version, you should select a different player with the Windows Media Rights Manager V7 identifier.

 

I have wmp 9, and am using OS X. I have a feeling that this problem is related to the wvm3 discussions that have been posted earlier. I downloaded, the vlc which has been discussed, and it plays most things. Short of that, I suppose I'm just out of luck, if the movies won't run in vlc.
