Hi, I'm trying to edit a .m4v video (H.264 video codec, AC3 (a52) audio codec) in iMovie '11 on MBP 13. The sound does not work. However, I can hear sound in quicktime player and VLC. But I thought that when qt works, iMovie works. Unfortunately, it doesn't. In my other MBP 17 the same video works fine - I can hear sound in iMovie '11.

It uses Quicktime to play back the video files and I think this is where my problem lies. Under XP I use *.m2v files (mpeg2) and their audio in a separate file *.ac3 (Doldy digital) and play back is 100% with audio. Under Windows 7 I do the same thing but Quicktime does not play back the ac3 audio (video is perfect).

If you want QuickTime to recognize and play Dolby AC3 encoded audio from movies, copy the AC3MovieImport component into the /Library/QuickTime folder as well. This definitely won’t hurt and you’ll probably enjoy it later.
