Bug Fixes in Multimedia
Introduce workaround to make dvd playback work.
Currently the MediaElement has QUrl as source property,
which of course fails for anything but actual urls.
Four options present themself here:
a) use QVariant so that a QML consumer can throw a url at us
AND a mediasource
b) introduce MRL support
c) provide two interfaces, one for url and one for mediasource
d) functions on mediaelement to expose advanced features (e.g. payDvd)
