how do you record a vid?

I want to post a vid of some vip hacks, but well i mean is i can't convert the .wmm file

There are plenty of screen recorders out there
Some examples:
Camtasia (Heavy)
Snagit (light, also a screenshot recorder)
Hypercam (Light, but sucks like shit)
Fraps (never used it)

EDIT: Also, wrong section

I would suggest ZD soft screen recorder......google it, download it, and try it out.

Fraps is the best recorder for games because it is especially made for recording just the game. Hypercam is also pretty good but it lag your computer a bit
