Radio now aac rather than mp3

[Paul]

All radio programmes are now ending up as aac rather than mp3. If I
remove all aac types from the options file then nothing is downloaded.
I have included the options files at the end of the output. Not sure
if it is relevant but I am abroad at the moment.
Any assistance would be much appreciated, thanks.
