You need to decode audio as well, something like:
gst-launch-1.0 uridecodebin uri=dvb://BBC%20NEWS name=d ! queue ! x264enc !
mp4mux name=m ! filesink location=news.mp4 d. ! queue ! audioencoder ! m.

Well that was informative! :-) I did as suggested and immediately discovered
that the
playbin is using uridecodebin not decodebin, so I tried: 

gst-launch-1.0 uridecodebin uri=dvb://BBC%20NEWS ! x264enc ! mp4mux !
filesink location=news.mp4

and it worked. Well when I say worked, I got video but no audio.

Huge step forward, but not a complete solution as yet.
