I want to record Runescape pvp vids with commentary what system should I use to do so? I want it to be easy and simple and something thats not too difficult to use

Download hypercam 2 (free software sticky. Alternatives are CamStudio or Camtasia). Set to record the screen size of your runescape box. The video should be in .avi format. Open up windows movie maker, file > import > select the file. Drag it to the timeline and select where you want text on the timeline. Hit insert text on video and just type what you want.

Well I got hypercam 2. When I set the window size while playing rs it goes realllllllllllly slow. Is it my computer?

Yea, you're computer doesn't have the specs.

Try running RS on lowest settings.
