dvbbasebin/mpegtsdemux not working properly?

Hello,

I am trying to use GStreamer for watching DVB-T. I use this pipeline:

gst-launch-0.10 dvbbasebin inversion=AUTO bandwidth=8
frequency=578000000 code-rate-hp=3/4 code-rate-lp=NONE modulation=QAM 16
trans-mode=8k guard=8 hierarchy=0 program-numbers=10123 ! mpegtsdemux
name=demux demux. ! queue ! mad ! alsasink demux. ! queue ! mpeg2dec !
xvimagesink

This pipeline works fine - but not every time. Sometimes it starts
playing after 5 seconds, sometimes it freezes, never plays audio, and
and never even shows an XV window, and sometimes it DOES show the XV
window, but then freezes.

Running it with GST_DEBUG=dvb*:5,mpeg*:5 I get this output:

(these are the final lines only, the actual dump contains several MB of
data).

I am using Ubuntu 10.10, libgstreamer is version 0.10.30,
gstreamer-plugins-bad is version 0.10.20 . Does anybody have an idea
what is going on here?

On a sidenote, why can't I also give the audio/video PIDs to dvbbasebin?
With only the service ID/program number, the bin has to wait for the PAT
to fetch the audio/video PIDs.
