Video Recorder That Won't Make The Screen Lag?

As many of you know, I'm trying to do the no damage challenge on ALtTP. What I'm wanting to know is, do any of you know of any good screen recorder downloads? I've tried the one included with VBA and it would make the game lag really badly. Then after playing back the video, it seems to be sped up and the audio is off.

I've also tried Hypercam and it lags the game and it wont record any sounds. Any help with this would be awesome. I'm looking to do this challenge tonight but the way things are going now with the video recorder problems, I won't be able to get around to it.

Change codec in the built-in VBA one.

How do I do that???
