This is done in the _firmware_ ... if you have trouble with some
channels, try to record with an older VDR (1.2.6 or < 1.3.18)
and replay the 001.vdr with tex_av_play.  But note that the
recording should include _one_ PS1 PES stream, not more and
_not_ less.  You may have look with the xlist tool from
the tools directory of the bitstreamout plugin, see for
PES frames with the id BD.

Ahmmm ... have you ever read the docs?
