Reasonable Screen Recording Software For Nowt

Not sure if it'll be useful to anyone here, but thought I'd jot a note. Yesterday I stumbled across a bit of software to record video files of you doing stuff on your PC. The most obvious use is probably to record tutorials with voice overs and stuff. So the above link is to a reasonable bit of free software to do the job. I've not been able to find any help files or anything, so it's a bit of a "follow your intuition" approach, but using their "lossless" video codec, the results can be quite good. Camtasia Studio, I gather is a more polished, sexy non-free product, that seems to get a lot of use by the pros, but for the rest of us, this free product might just suffice.
