With mpegts from git master and 0.10.36 live mpegts sources are no longer
played back in a pipeline.

Confirmed for playbin2 and manually constructed pipelines
(http://lists.freedesktop.org/archives/gstreamer-devel/2012-February/034961.html).

Probably has something to do with commit

    mpegtsdemux: only offset timestamps when live

    This code is to sync to a live source when there is a delay
    between start and when we receive the first buffer, so it does
    not make sense in a non live case.

    This fixes playback of streams where the input timestamps are
    based off some arbitrary offset.

Reverting this commit solves the problem.
