    Hi, Zoltan Hidvegi!

    No, it doesn't. May be I'm wrong but I've found that frames on DVDs
(at least from filter's point of view) are progressive interlaced so I
didn't find a way to split one frame in two fields, drop one and join
other field with field from next frame later. Again, I may be wrong in
that. I just didn't find another way then (a year ago). I've also tried
detc filter but I've found it worse than dint filter because it leaved
more interlaced frames and it looked bad. :(

    With best wishes.
