Can I do a screen capture while recording a video in MC?

MC video can only record the audio and video that come through the webcam.  The reason for this is that everything in MC runs through the browser without any additional installation.  In order to do screen capture recording, you would need to install an outside tool like Jing, Camtasia, or another tool.  Jing is the best free solution for this because it will allow you to do up to 5 minutes of screen capture video, then they host the file and give you a link to use.  If you get Camtasia or another video editing tool, you would need to host the file yourself or upload it to somewhere like YouTube to get a link to use.
