Got a good result with camstudio, once the codec used was not too big
nor too cpu intensive (made a record at about 20fps, then replayed the
12 minutes at 30fps to reduce the movie to 8minutes).
I did not capture the sound but it was possible.


Just do not ask it to do a flash encoding. Better process the frames in
your video editor.


Otherwise, I got good echo from fraps, but not free.
