I have a good amount of M4P files scattered throughout multiple folders. I would like to get an app that can scan all the folders and then convert whatever M4P files it finds to mp3.

When I've wanted to convert to mp3, I just burned a CD in iTunes (usually burning to an image, IIRC), and re-reipping the CD to whatever format I wanted.

M4P Converter for Mac OS X has been revved to version 2.1.4. It’s a DRM copy-protected audio and music converter designed for converting DRM protected music to unprotected MP3, AAC, AIFF, or M4A files ...

Updates on the Wolverine MVP 60GB Portable Multimedia Storage and Player, converting M4P files and more.
