KIO::PreviewJob was made for this kind of things, it also does not involve
loading the file (which may play a sound even if the widget is not
visible), seeking, pausing and then grabbing a QWidget snapshot. the only
requirement is for ffmpegthumbs thumbnailer to be installed

some form elements were not working before either so the only
regression here is the seek slider, if KMediaWidget is used the
whole custom controls code can be trown out I suppose but I'm not
sure if the controls should be embeded along with the video or
they be can/should be separate
