In my experience it increases PSNR somewhat. Of course, PSNR isn't
everything, but with such small differences it's nice to have a
quantifiable comparison.

As far as I know, vhq is just an alias for mbd=1. You might as well
try mbd=2, though. My tests have shown it to increase psnr somewhat,
again.
