Summary:
As I'll have to record some video presentations in the upcoming future and lately I've been thinking about publishing some video screencasts - today I've spent some time on checking and setting up some tools to do this on my computer. I've decided to post my findings and final settings.

It seemed like there were really two options for straightforward unix-like tool to do the job:

I had some audio related problems with both programs - both recorded video with audio going out of sync, or nosie. I've found this: http://karussell.wordpress.com/2009/11/18/recordmydesktop/

And the options suggested in one of the comments are working fine for me:

--v_bitrate 2000000 --s_quality 10 --delay 1 --fps 20 --overwrite -device plughw:0,0 --no-wm-check --buffer-size 65538 --freq 48000 --quick-subsampling --on-the-fly-encoding

I've spend few more minutes to "import" this into the gtk-recordMyDesktop front-end to recordmydesktop. My .gtk-recordmydesktop file now looks like this:

#Order and overall number of lines must be preserved
