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.
