    I have the same problem - my wedding footage is from a Praktica DVC 5.2.

    Quicktime player will not play the audio either. Media Player Classic with Quicktime Alternative will play the audio.

    What we need is a MOV to MPEG4 transcoder which will rip the streams from the MOV container and poke them into a standard MP4 file (or AVI), without processing them, taking the rather flaky quicktime out of the equation.

    Can anyone out there help either of us?

    I've foudn my own solution - and it works brilliantly.

    It does NOT transcode. It simply rips te streams from the mov file (video and audio) and plonks into an .MP4 container. this is a copeltely lossless transcode.

    Many of you will be interested to know that not only are the files 50kb smaller, but they consume around 70% less cpu ticks to decode during playback. Either Quicktime is very very very poorly coded as a container or quicktime doesnt support DXVA playback on a PC. Either way - mucho suckings.

    MediaCoder - more than a universal audio/video transcoder

    1) download media coder. Drag in all of the files oyu want to transcode.

    2) On the video tab select Copy Video. This will grey out transcode options.

    3) On the audio tab, select Copy Audio. This wil grey out transcode options.

    4) on the container tap select MP4.

    5) Hit Start

    6) start using your lossless MP4 versions.

    This procedure will likely work with most digital cameras that record video in the MOV format these days. Tested and proven with Praktica DVC 5.2 @ 1440 x 1080 29.97 fps.

    Cool beans - That was my wedding footage I couldnt get working!!!!

    OK the solution is not yet perfect.

    The files go out of sync slightly. Tried making just an MP4 file and a WAV file and dumping themo nt he tieline in Vegas but still out of sync, so it must be something to do with the extraction process. Will keep you posted via this thread for future users info.
