In http://www1.mplayerhq.hu/MPlayer/samples/evob/ BLACK.EVO and
MAININTRO.EVO contain E-AC3 streams. In order for ffmpeg to be able to
demux the streams in these EVO's it's necessary to either apply the
mpeg.c patch I posted previously, or just hack mpeg.c to identify
substreams 0xc0-0xcf as AC3.

Simply running ffmpeg -i <file> is sufficient to test the patch.
