Because of that last line I suppose lame can't decode m4a files. As I 
don't have any m4a files myself, I couldn't test it and I thought you had 
already verified that lame could convert your files with the command you 
posted. But I can't tell you which program you could use instead of lame 
to do the conversion. Maybe you could try the soundconverter package 
mentioned in the forum thread you posted.
