As another suggestion, fraps is good. It's really easy to use, records sound even with the free version. main 2 drawbacks are, without buying the full pack, you only get a 30 second runtime on each video and (i'm not sure if this is only with free or even on full) but the video sizes are massive because they aren't comressed. 30 second videos can be anywhere between 20 and 40 megs, or higher....
