I've experienced the problem he is having. Usually anime is telecined, 
but there may be cuts or edits within the movie on the DVD that break 
cadence, or small stretches of true video-rate material intercut with 
the telecined material. Normally you don't notice this on your TV set, 
but it can be a real bugger to sensibly get a good encode of it. You'll 
end up with a few interlaced frames here and there.
