I tried to use the command line like you have below.  I did upgrade the 
ivtvdev_drv.o to 0.10.6.  I am assuming this has xv support.

When I run the command I get in the bugreport file:
video_out_xv: Xv extension is present but I couldn't find a usable yuv12 
              Looks like your graphics hardware driver doesn't support Xv?!
main: video driver <xv> failed
