Re - encode mpeg2 video track and preserve wierd flags

Anime DVDs usually have wierd flags (VFR or progressive flagged as interlaced or progressive + interlaced fades flagged as interlaced, OR progressive with interleced credits flagged as interlaced).

If i re-enocode the video track from a DVD (demuxed with dgindex) as interlaced on any encoder i will lose quality / eficience.
If i encode as pulldown i will have a mess if interlacing / progressive patterns on the movie.

My question:
Is there any encoder able to re-encode detecting progressive - interlaced ON THE IMAGE and flag the stream correctly
Or
re-encode detecting the progressive - interlaced on the image and copy the original flags to the destination stream
Or
Remove those flags and encode detecting the interlaced - progressive on the image and then re-flag with other tool the resulting stream with the flags of the original?

Yes this is a little confusing (for me).
I dont know why they do that.
Why not encode the film sections with the correct pulldown and the interlaced sections as interlaced? Then i could cut and encode each section with the appropiated settings.

Thanks
