None of those work with MPlayer I'm afraid. I also tried -vo directfb
instead of dfbmga, but no difference. :-(

I hope it's just MPlayer; having to use sudo for that won't be too much
of a problem as long as VDR's softdevice plugin (if and when I can get
that working at all!) will work without being root.
