The two samples I previously uploaded to upload.mplayerhq.hu in
directory latm-danish should do.

With my patched version:

mplayer danish-1.m2t : sound works (using faad)
mplayer danish-1.m2t -ac faad : sound does not work

If you do a msglevel all=9 you can see that in working case above, the
audio stream has been read a bit before faad tries it (as it the tries
ffaac first). Without my patch neither case works.

The sample danish-2.m2t works in both cases with my patch, without my
patch it only works without -ac faad.

As my patch is not enough in the danish-1.m2t -ac faad case above, an
even better probing for correct place to start decoding AAC audio is
needed.
