OK Sorry I had to leave for a bit.
To make VLC your default media player; While in Limewire, click the library tab. Now Click explore (lower left corner) This will take you to your saved/shared folder outside of Limewire. Now Rt. click on any file. Go to Open With > Choose Program. Now click VLC. Put check in Always use this program...> OK.
To learn about VLC, go to the download site and look for instructions there. I don't use it so I can't offer any advise.
Hope this helps.
