Why can't I play more than 1 videos at a time in Windows media player?

I have windows media player 10.

One reasons I prefer earlier (pre-8.0 I think?) versions of Windows Media Player is the fact that you can have multiple video files playing at the same time, all in seperate windows.

Is there a way to do this with the newer versions of Windows Media Player, as in
8.0 and 9.0+?

 

Go to Program Files/Windows Media Player folder. You will see mplayer2.exe. You can run this application as many times as you wish and open different media files in the same time.

 

That doesn't work, it will just keeps the same video playing and won't open up a new instance of the player.

 

WMP 6.4 - mplayer2.exe
View > Options > Player tab > Check Open a new player for each media file played

 

I have windows media player 10 as stated above. I need to do this with this version. 6.4 I can't use as it's too old to work with new codecs.

 

You can't do that.
You can only have one Windows Media Player versions 7-10 running at a time.
You can have multiple Windows Media Player 6.4's running at a time.

Example: 1 WMP 10 and 4 WMP 6.4 can play.

There are codec packs that allow WMP 6.4 to play many newer audio and video formats, as long as they are not DRM protected.
