This may appear to be a rather simple queistion but where do I go to change the default media player settings - for example each time I play a video I want to use Windows Media Play instead of real player.

I'm assuming XP?

You can either set the default media player in Control Panel > Add & Remove programs > Set program access and defaults OR if you wanna change only a certain filetype, right click on the file and click Open With > Choose program, then select what you wanna open with and check "Always use selected program to open this kind of file"

Sorry yeah it was XP. Thanks for the help - I had changed it the default settings before but I just could not remember how I did lats time. Thanks again.
