  It sounds like the driver is giving bottom-field-first frames instead
of top-field-first.

  In the V4L2 spec it says something about "PAL interlaced is bff" but I
didn't believe it (it doesn't make logical sense to me to change it for
PAL).

  So, um, what's the deal?  If you do give bff frames, do you indicate
that somewhere?
