if i have windows xp and purchase a mce remote with the ir blaster etc... Do i need any software to use the remote solely for windows media player or does it only work with the windows media center program.
You should look into Eventghost. I configured Eventghost for a friend to use with XBMC and it is very flexible and free. While you're at it, you should look into XBMC. Windows Media Player is very basic.
