I just noticed my get_iplayer has started  throwing these error
messages, which I "fixed" by commenting out the lines in the files.

The message that concerns me is

WARNING: Deprecated option in /home/kevin/.get_iplayer/options: 'aactomp3 = 1'

which means my files will no longer be converted to mp3. Did I miss
the discussion somewhere that concluded conversion to mp3 would be
removed?

What is regarded as best practice to create mp3 files today? I suspect
AAC is now the preferred format

Thanks
