Attached is a patch that fixes bob displacement for overscan
with XVideo, while letting XvMC still work when there is no
overscan.

It appears the nVidia closed source drivers no longer
require a bob displacement, as of v66.29. Of course, this
is a blessing and a curse, the automatic displacement
means we don't need a displacement normally, but it does
not work at all when we do over/under scan.

I've tried the obvious of applying displacement only in the
overscan or underscan cases, and also the less obvious of
calculating the normal displacement and over/under scan
displacement then applying the difference. Neither worked.

Anyway, I'd like to know if the patch is a regression
for anyone before applying it.
