I'd suggest you deinterlace before transcoding, via whatever means you
can. Since transcoding doesn't have to be real-time, you can use a nice
high-quality deinterlacer. OTOH, since you're scaling down by quite a
bit, even just separating the fields and doubling the framerate (or
discarding the odd fields) would alleviate this problem.
