Sure! I'm using videolan as a streaming server for channels received
over DVB, multicasting them over ethernet. I'm trying to limit the
bandwidth consumed as much as possible. As I don't need the MHEG data, I
removed it.

In the UK, the interactive data is shared between all channels on a mux
(transponder), so you end up with all the interactive data for all
channels being duplicated on all the streams output by videolan (at
least on the uk "MUX 1" you do). I've not really investigated the other
MUXes yet.

I could implement a configuration option for dvb to select which stream
types should be output, if people think it might be handy? 

Note that the patch as-is doesn't select _which_ streams, just which
stream _types_... so you still get multiple audio/video streams if they
are present.

I'm actually writing a UK-specific MHEG decoder at the moment, purely
out of interest.. Zlib-deflated CORBA was the last thing I expected to
see coming out of my DVB card though! :)
