Well, this video is a screencast recorded during the intensive developement of the first release in 2010.
Please note that the operative system is entirely copied into the memoria RAM and then running from it (allowing you to eject the DVD or the USB key), this means that the system is running extremely fast..
Also note that in this video, hard drives are not "mounted", that means they are not in use (sometimes it may be useful for the user).
It corresponds to the first two lines of the options of the live boot:
io Live to RAM
io Live to RAM (no mount hard drives)
You will need to get a computer with RAM > 2Go to use this option, otherwise use:
io Live USB
io Live USB (no mount hard drives)
With those two options, you can't eject the DVD (or USB key), because the operative system runs from this media.
