The story so far...

It seems that get_iplayer with aactomp3 does a cracking job copying across the metadata, including cover art.

However, when converting the m4a files to mp3 using WinFF, some of the metadata goes AWOL.

And the rest of it doesn't show properly in media players such as Windows Media Player and Total Recorder, though it looks impressive with MediaInfo program.
