Due to a lack of support for an audio codec (Windows Media 9 Voice) in most media players (quicktime, flip4Mac, etc), Mac users must download and install Windows Media Player 9 from this link:.
download --> Windows Media Player 9 for Mac OS X
Once installed, right click any wmv file on your mac and choose "Get Info". From the info screen select "Windows Media Player" from the "Open with:" menu to set Windows media player as the default application for wmv files.
Important: If you want to view the windows presentation, please use firefox as your web browser. Safari doesn't seem to work well with windows media player...
