As a first stab, I suggest installing rtmpdump and trying again. 
get_iplayer will automatically use rtmpdump instead of flvstreamer.  On 
my Lucid system I got garbage when downloading your programme with 
flvstreamer, but rtmpdump produced a playable file.  I didn't see any 
errors from mplayer about missing MP3 headers, even in combination with 
flvstreamer, but I have a slightly older version of mplayer here.
