Have you actually looked at them and confined that they are really interlaced? It should be all progressive, maybe except credits which are quite often added as interlaced. 100 frames out of random 1000 being interlaced sounds very odd.

Check it in something frame accurate at 1:1 pixel, e.g. VDub with ffmpeg input plugin.
