For anyone else having this issue in Windows Vista:
Go to the Control Panel, click on "Classic View" in the left hand menu,
double click the "Default Programs" icon.
Now click on the "Set Default Programs" link, highlight Windows Media Player
in the left hand menu, choose "Set this program as default". Click "OK"
With the Default Programs Menu still open: Choose "Set program access and
computer defaults"
Click the double arrows for Custom. Make sure all the selections have a
check in the box beside "Enable access to this program" Make the correct
selections for your browser and the default media player as Windows Media
Player. Ok out of everything.
For some reason after installing some codecs (even without other players)
the file association changes. Hope this works for all.
