i've got a transport stream which i captured the way it fell from the sky (dvb-s broadcast) and it has discontinuities at the beginning
these cause tsdemux to not start playing whatsoever

ERROR: from element /GstPipeline:pipeline0/GstTSDemux:d: Internal data stream error.

and mpegtsdemux (when using my bdremux tool to convert from ts to m2ts) to get stuck after 1 MB and never get to EOS

this can be also achieved by building a manual remuxing pipeline:
gst-launch filesrc location="20120420 1415 - ZDF HD - Die Küchenschlacht.ts" ! mpegtsdemux name=d d. ! queue2 ! video/x-h264 ! mpegtsmux name=m m2ts-mode=true ! filesink location=bla.m2ts d. ! queue2 ! audio/x-ac3 ! m. -v

the log suggests a queue problem:

remuxing the audio or the video elementary stream seperately will work fine though
