OK, I think you just need to update ffmpeg to make this work.  I 
downloaded the latest from:

http://ffmpeg.zeranoe.com/builds/win32/static/

I configured WinFF to use that build (in Preferences) and added

-id3v2_version 3

as an additional ffmpeg command line parameter.  With that, I could 
convert a M4A file downloaded by get_iplayer to MP3 with metadata tags 
copied across.  The metadata in the resulting file could be viewed in 
Windows Media Player.

For whatever reason, the ffmpeg build deployed with WinFF (dating from 
last October) couldn't copy MP4 metadata to id3v2.3 format in MP3 files. 
  I didn't comb the ffmpeg repo to find out the details, but the latest 
build seems to work.
