Because MPEG-2 audio is rather uncommon (DVD's and DTV, the only common mediums I can think of that use MPEG-2 video, usually use AC-3 audio) I'm even having trouble finding Linux-aimed tools to work with it. Let me know what solution you find, I'm curious to hear it. Yeah, MPEG2Works is probably your best bet, it’s the only Mac program I know of that claims to be able to work with MPEG-2 audio.

The file format is the VR_MOVIE.VRO file that you can find referenced on the web (if you just google on that name). I don't know much about it, but I know these things: 1. There are multiple MPEG movies in there. At least the crappy Winderz programs that came with the camera can figure out where scenes start and stop. 2. When the Winderz software breaks it out into a bunch of files, one per scene, it creates a bunch of MPEG-2 files. The audio is muxed MPEG-2 audio. Which, as we all know, Quicktime will play but will not manipulate. I just found http://www.gemini3.co.yu/tosa/mpeg2works/ this software and I'm going to give it a shot. they claim to be able to do this sort of conversion. The camera is a Hitach DMZ-230a.

AC3, MP3, PCM, etc.?) Perhaps more useful would be the make and model of the camera. Also, I assume the file output from the camera is some sort of progressive stream, like a .vob or .avi? Or does it give you the elementary streams (a .m2v for the video and, say, a .ac3 for the audio)? Glad to see you using OS X. Nice, ain't it? What format is the audio? (E.g. AC3, MP3, PCM, etc.?)
