Sorry, I am just to lazy to properly attach patches.

What do you mean? Btw. what really confuses me is that ffplay -sst 5
plays some foreign language while when ffmpeg remuxes the 0.5 subtitle
stream I get English...

It works directly for me (svn up, I applied the encoded buffer size fix), with this command line:
ffmpeg -i sample-dts-not-valid-dca-frame.m2ts -ac 2 -scodec dvdsub test.mkv

Colours are "interesting" as always though.
mpeg is a bit of an issue, because the subtitles start only so far in I
guess, so ffplay doesn't know it is there or something and I don't know
which -sst to specify (maybe I should just play it with mplayer :-P).
