Disabling PTS synchronization is sometimes desirable when services switch
between regional and national broadcasts that may have different PCR references
but continue to the same Teletext stream. Where the PCR reference is different to
the Teletext PTS, Teletext cannot be synchronized to the output video and will be
continually dropped.
