[HELP] Movie Trailer - Fix needed

[Miranda]

I've been given a DVD-R, made from an early 1980s PAL VHS dealer tape. To make matters worse, the tape was an NTSC to PAL conversion. The DVD is interlaced, bottom field first. The trailer itself also appears to have baked in interlacing (ghosting on some movement). I believe the trailer also runs at the same speed as the original, so will not require any slowing down.

I need to convert the trailer to progressive 23.976, and hopefully remove the baked in interlacing.

There is no other source for this trailer, unfortuantely.

Is there any way to fix this?
