I'm in the youtube business and I was curious to know

Recording Games:
Fraps. (30 Seconds Free)


Recording Desktop:
Camstudio.
Hypercam.

I do agree with Hours on fraps, Its the best for recording in game things, Although it makes your game a bit choppy if your not running a awesome computer, So if you get fraps, Lower some of dem graphics if you need to! Although fraps is 30$, Its about 90x better than anything you can get out there.

Alright thanks guys, big help. Never doubt the toribash community.

Or you can get already registerd version of fraps on Pirate bay

The most usual is fraps
