Hi Carlo Thanks for the suggestion. I had noticed that ffmpeg kept cropping up in discussion groups, but I couldn't understand how it all fitted together with containers and what have you. It seemed to be aimed at tech fanatics!
I was going to buy WannaAudio to see if it would work when Ronni's instructions on using iMovie were posted. Advantages of the iMovie method were that it worked and there was no need for more software.

I have had mixed success with it as it depends on a number of plugins that must be downloaded separately. Once it it running, drop the file on the left side of the app window and select the preset "Movie audio to mp3". http://www.ffmpegx.com/ Failing that you could be a trail blazer and try WannAudio for the rest of us. :-) Regards, Carlo On 01/07/2012, at 18:09 , Alan Smith wrote: > Hi Ronni > > Yes, a possible solution.
