Comment(by mythtv at glidos.net):

 One more thought. It just struck me that it might be better to combine
 !frame->interlaced_frame with the parity flag, rather than with tff, as
 below
 {{{
     filter_func(
         filter, frame->buf, frame->offsets, frame->pitches,
         frame->width, frame->height, dirty | !frame->interlaced_frame,
 frame->top_field_first,
         dirty);
 }}}
 That, in a way, turns off the algorithm for progressive frames, making
 both the constructed frames exact copies of the original. For the mixture
 of tff interlaced frames and progressive frames that you are seeing,
 results should be the same, but this version should also work for a
 mixture of bff interlaced frames and progressive frames.
