I Thought I'd found the answer - I replaced '-acodec libfaac' with 
'-acodec aac -strict experimental' in the transcoding.profiles.xml file. 
Running the ffmpeg command with the parameters from 
transcoding.profiles.xml works OK and creates a valid file, but when I 
run the same thing through mythpodcaster I now get this error after 
about an hour of transcoding:-

Does anyone have any idea what could be wrong?
