In case anyone is still interested in using libavformat to generate TSs
that vlc can read, I searched for my old patch, I reworked and
simplified it, and I added DTS support...

The result is attached to this email.

Yes, I know that the patch is wrong in many ways, and this is not a
submission.
But as a matter of fact, vlc 0.8.2 (well, the "0.8.2-svn Janus" that is
installed on my debian stable machine) can succesfully play TSs
generated after applying this patch, and does not complain :-)
I just post this patch because maybe someone interested in ffmpeg / vlc
interoperability can use it as a starting point.
