First of all, try using GStreamer 1.x and if you can't at least use the
videomixer2 element in 0.10. That should already make many things
better, especially regarding synchronization.

Then also note that videotestsrc is not needed here (videomixer can draw
a background) and the same goes for the videoboxes (you can configure
the alpha and the position on the videomixer sinkpads, see the docs).
