<div>That's strange.&nbsp; This has not been a problem for our own use
of &quot;MPEG2TransportStreamFromESSource&quot; (in our
&quot;wis-streamer&quot; application).&nbsp; Note also that these
presentation timestamps still end up getting used as the PCR values in
the resulting Transport Stream (they just don't, with your
modification, get put in the PES header), so there appears to be
nothing wrong with those presentation times per se.</div>
