In a hardware decoder, PCR is used to synchronise your local 27MHz clock to the
broadcaster's 27MHz clock. PTS is the presentation timestamp, measured against
that 27MHz clock. Packets are removed from transport buffering at their decode
time, which is DTS if present, PTS if no DTS present (see section 2.4.3.7's
description of PTS and DTS). I would not personally expect decode times to go
backwards, and certainly not by a large amount - this could be used to detect a
probable discontinuity.
