Windows Nedia Player
 

I hope someone can help me. Most of the time when I download a movie or some video file and try to play it in Windows Media Player I get an error message saying "Windows Media Player cannot play the file. The player might not support the file type or might not support the codec that was used to compress the file" Is there something I need to be allowed to play these files and if so what is it and where can I get it.

Thank you
