I updated my Extract Movie Soundtrack 2.0 freeware app. Now it is an universal application.
This small utility application was created to export the sound track of QuickTime movie files into AIFF files. This way I can take some of my movies and get the sound track into iTunes. In iTunes you can use the Advanced menu to convert the AIFF to MP3 or AAC to save space. Chapters in the movie are preserved.
