We don't give much support on GStreamer 0.10 anymore. Though using
GStreamer 1.2 you no longer need videobox. Here's a non-tested example:

gst-launch-1.0 uridecodebin uri=file:///myfile ! videoconvert ! videoscale ! video/x-raw,width=200,height=200 ! m.sink0 \
               uridecodebin uri=file:///mysecondfile ! videoconvert ! videoscale ! video/x-raw,width=640,height=352 ! m.sink1 \
               videomixer name=m sink_0::zorder=1 sink_1::zorder=0 sink_0::xpos=220 sink_0::ypos=76 ! videoconvert ! autovideosink

cheers,
Nicolas
