The mkv is just the result of feeding the vob into mkvmerge, not reencoded, just remuxed.

So you would suggest

a) -vf fps=30000/1001,fieldmatch,decimate=6
b) -vf fps=30000/1001,fieldmatch,decimate=6,yadif=deint=interlaced
c) -vf fps=30000/1001,fieldmatch,yadif=deint=interlaced,decimate=6

won't a) leave interlaced frames?
