lettoyou quickly want to record frags and stitch the clips together? - shadowplay
you want to make an eye-appealing fragmovie? - use lawena
theres is this tool which in combination with lawena should let you skip having to stitch the tga and wav files together in virtualdub but i personally didn't get it to work
you'll also need a software like sony vegas if you wanna edit the resulting avi files when you put the together
beater made an excellent video on the basic lawena recording process:
