I think there are 3 options, and which one probably depends on the deinterlacer
algorithm:
  1) don't deinterlace them at all
  2) implement a degenerate deinterlacer mode in each algorithm for these cases
  3) for adaptive deinterlacers, maybe deinterlacing by duplicating fields to
produce a 'full' set would produce acceptable output (might be best implemented
as the 'degenerate' handling in option 2), inside each deinterlacer algo.

Maybe other people have better ideas too.

When I get time, I'll try and confirm that it's disconts causing the problem -
I now suspect it's the most likely reason.
