Try Hypercam 3. It has the best free version of them all.Note to haters who say it has poor quality, this is fixed easily by going to settings and changing the compressor to "Uncompressed Video".
If Fraps lags, try going to the Movies tab and going to Video Capture Settings, then click 29.97.
What about the nasty watermark?
I can't use fraps because it makes me lag like stuff
also, fraps; 1 1/2 minute video = 2 gb, what the christ
