This can very well be. I haven't looked at or changed the av_pes2xxx
programs for a while. The versions in the driver are more up to
date. I don't think I want to put too much work into that, because
av_pes is not a standard format and will soon vanish from the driver.
av_pes2ts was the one I did last, so that might work better.
I would like to stress once again, that TS is the natural format of
DVB and that the DVB API is mainly concerned with this format. So that
in the future we will mainly concentrate on programs that use TS
and/or transform other formats from/to TS. I might add that TS is also
the best format for streaming MPEG.
