If Iam not too late a can suggest several tools for desktop recording.
the first one which I like most is screen vidshot
. there are 3 different modes of recording (very useful)
after, there is 1 more, freeware, its called vidshot capturer (same web)
and the last one whick i am practising now is presentavid
. Its will be very useful for those who are making a video tutorial or something like that. there is an oppotrunity to add watermarks on a video, something like what they using in comics +) or just a simple logos or whatever, so try it, everything is a free to try
good luck everyone +)
