If the main video was interlaced then the stills need to be treated
as interlaced.

Yes, I think that would be a good idea - otherwise you'll end up
with progressive frames.

One question just hit me...
Did you create the audio track in little pieces (individual .mp2 files)
that were catenated together or did you do one long audio capture and
encoding? I'm wondering if the playback problems you're having are
due to discontinuities in the audio stream at the splice/join points.

Unless you place a 'yuvdeinterlace' command in the pipeline the
interlacing will be preserved.

If the main files are 768x576 then scaling back to the DVD frame
size is not just a "good idea" - it's required ;)
