you guys are doing things the hard way.
Use Sony Vegas Movie Platinum 10.0
it also has a built in youtube renderer and uploader, that renders and uploads it at the same time with your youtube login. took me like 5 min or less for the 250mb vid I posted on the last page at 1080p HD
I also use fraps. thats pretty much the standard screen capture
I use 30FPS for recording . its noticably smoother, and doesnt tax the machine during recording on larger battles. also, most AVI or MP2/4 formats render at just over 27-29 fps so there is no need for more than that or you will just inflate your file sizes.
