ISO/IEC 13818-1 2.7.5 clearly states :
"A decoding timestamp shall appear in a PES packet header if and only if
the following two conditions are met :
 - A PTS is present in the PES packet header
 - the decoding time differs from the presentation time"

Thus, this latest change makes VLC non-compliant to the MPEG-2 spec.
