As you say, --raw won't help you.  Your problem is that your connections 
are being dropped, most likely by your VPN.  Others have had the same 
problem.  But rtmpdump can't always detect that a stream was dropped. 
And when rtmpdump exits without error, get_iplayer doesn't know any 
different.  Skip --raw and let ffmpeg re-mux the .flv file as normal. 
The output from ffmpeg contains the duration of the input file, which 
should tell you whether or not the file is complete.

Estimated mode sizes can be viewed with --info, but don't bother.  The 
estimates can be off by 10%.  There is a nominal duration value in the 
--info output that is usually more accurate, but then you already know 
how long the programme should be.
