This link should help you out?Windows XP: Learn how to expand your workspace with multiple monitors

Nope. I know how to do that.
I need to display 2 diffrent movie files on 2 diffrent monitors.
Windows media player will not alow it.

You could install another difffrent media player and drag it to second monitor as directed on the link.

No, it will only allow one instance of media player at any one time. What you need is an extra player such as: Free-Codecs.com :: Download Media Player Classic 6.4.9.1 : Media Player Classic is an enhanced version of Media Player 6.4

So on the first monitor you'll be playing your video file using normal Media Player, and on the second monitor, you can use Media Player Classic.

Yeah that will work.
But Id rather use one program. Im trying this for a business adventure. hahaha.

Sorry imap, it isn't possible to do this in Media Player, at least anything above version 6.4, or unless you want to embed your video's into web pages. You might want to complain to Bill Gates about that one lol.

You can however open multiple instances of WinAmp (Download Winamp Media Player 5.53 - Download Winamp Media Player for Free). To open a second WinAmp instance, press [CTRL] + [ALT] + N
