Well that's only due to Debian problems ('oldness' and licensing issues
with mp3).
I notice that i've got libavcodec51 installed, but it's done me no good

Looking back at my script I wrote back at Christmas when the iphone
option stopped working and my programs started coming down in aac I seem
to have a faster solution which works for me;
