Nice to know someone else in the NorthWest is using Nova-T cards :)

It took me ages to realise that there's a 'Winter Hill B' broadcasting the 
two Freeview Muxes on different frequencies - now they're the strongest 
signals I get! =)

It's not a bug... you're just not looking in quite the right place - let's 
take this sample output from the main BBC mux:

<transponder type="T" freq="754167000">
<service id="4168" ca="0">
<description tag="0x48" type="1" provider_name="BBC" service_name="BBC ONE" />
<stream type="2" pid="600">
<stream_id id="1" />
<descriptor tag="0x11" data="ff" text="." />
<descriptor tag="0x07" data="0b402403" text="...." />
</stream>
<stream type="3" pid="601">
<stream_id id="2" />
<iso_639 language="eng" type="0" />
</stream>
<stream type="3" pid="602">
<iso_639 language="eng" type="3" />
<stream_id id="6" />
</stream>

The 'service id' of 4168 is completely irrelevant for 'dvbstream' purposes... 
VDR only uses it to uniquely identify channels (I think).

In this output fragment three seperate streams are described: 

 - a single type "2" (video) on PID 600
 - two type "3" (audio) on PIDs 601 and 602

So, to view, you'd use

  dvbstream -f 754167 -cr 3_4 -qam 16 -o -ps 600 601 | mplayer - -nocache 

etc.

Have fun! :)
