Introduction to add-on

great Add-on; the voices are very good in at least 2 languages I have tried (English & Spanish). I wanted to share it with my colleagues but I won't direct them to the video. The background music makes the reading of the selected text difficult to understand... even when in the screen the Artificial Silence (?) sign appears, there is still upbeat music

Thanks for the enlightenment. I guess that having made the video myself I'm just too used to it and I can't easily detect defects.
I still happen to have the source files of the video editing; I'll upload them here if someone would like to tweak and improve the video. Editing just takes so much of my time that for the moment I prefer to focus on the add-on code rather than on the video itself.

Edit: just noticed the the video sources are some 180 MB, too heavy for my ADSL. But probably nobody would use them anyway.
