I aim to have a video as backgrund for the upper half part of the center-area
of a side. Just trying to build this using
http://de.contaowiki.org/Hintergrund_Video

In doing so, I faced the problem that saving a change to fe_page.html5
in /files/templates is not allowed by the Backend (403). So I changed
it by FTP. To do s.th. behind BE's back... is it ment this way?
