FMLE wont see VLC Im pretty sure about that.
If you are on PC you can always try the program with the very strange name SCFH DSF. Its a screencapture program and you would have to read up on how it works but it works good once you figure it out.
Vidblaster have an unlimited try before buy version but with a watermark in the upper right corner of your video.
I suggest you move over to google+ hangouts instead of Skype. Google+ hangouts is free and works up to 9 people with live video and vox the same time.
To capture the sound from skype or a google+ hangout if your on a PC I guess a program like virtual audio cable is what you would need. If your on mac its soundflower and LineIn you need.
