I just grabbed a bunch of DVDs I have at hand and actually only 50% of them are using default mpeg2 coefficients. There are considerable number of them that uses s170 and i470. Also I had one that uses FCC. So I guess its no good to just apply this filter to any DVD you have.
P.S. Is it possible to write a filter that returns coefficient type, so that conditional usage of ColorMatrix is possible?
