Thanks for the help. That program does not convert a quicktime MPEG-4 to MP3. Does anyone still know of a free program to do this or not? Thanks for the help.
I have purchased this one once and still using it. I converts MP4 to MP3.
I don't know if the trial version will do this, but it says 21 day full functionality, so give it a try.
DBpoweramp looks good but only 21 days free and I'm always wary when there are little "extras" you can purchase (got caught with Nero on that one - bought the program and then pay (a lot) extra to get the audio filters and DVD burning capability after they expired after 30 days from purchase) :
As I keep saying (too often I think), I use Ultra MP4 video converter. Haven't found anything it won't convert yet (fingers crossed) including audio from video files etc.
