Good screen recorder help?

-I have Cam Studio, but I am recording Roblox videos and the quality sucks.

I also have Total Screen Recorder full version and it sucks also.

What is a good screen recorder for Roblox??

Also I have windows vista.Having a fast PC helps with the quality of the screen recording. Try using My Screen Recorder. It is easy to use, and creates standard AVI or Windows Media format files.
