 Hi, Steve

 I'm afraid I could be of no great assistance to you, since I'm just a 
medium-level Windows user of get_iplayer :-(
But, two points there:

1) Is it any specific reason to your OS that you're still stuck with 
FLVStreamer v2.1c1?
 Can you find and use instead a binary of rtmpdump v2.3 compiled for Ubuntu 
8.04 Hardy?

2) Your version of FFmpeg suggests it comes from git, yet all other info 
about it is quite old:

 Recent patches of get_iplayer that remux AAC audio (derived from flashaac 
radiomodes) into an MP4 (.m4a) container,
require very recent versions of FFmpeg.
The win32 binary that I'm using has this to report:

FFmpeg version git-N-28975-gd459d8e, Copyright (c) 2000-2011 the FFmpeg 
developers.
