If anyone plans to create a video tutorial I could recommend CamStudio (
CamStudio - Free Screen Recording Software). It´s free and it produces small swf files and html starter.
I have chosen for a minimum size (roughly 1 MB/min zipped):
Initial AVI codec: Cinepaq
15 fps AVI, audio default
Transcoding to swf: 15 fps, 15 Keyfps, audio default
Edit: Screen size was 641x500 p that equals the welcome bar, breadcrumb and the lower screen except the sidebar. To capture the other areas I moved the browser window.
