    I have spent hours trying to find software for this and cannot find a thing. MP4Box and YAMB are Windows only, even tried with CrossOver but no luck. I used to use avidemux but that crashes as soon as I open it. Can someone please suggest a solution?

    Thanks.
    Marcel.

    Your title has nothing to do with your test. The answer to your title question is "no." You can't transcode video between lossy compressed formats with no loss of quality.

    You can use .mkv on your Mac. Why do you want to transcode?

    Who says he does?

    I've rewrapped MKV to MOV using MPEG Streamclip, with Perian installed. I've had issues going to MP4, and heard of times when it doesn't work at all, but all of my MKV to MOV attempts have been successful.

    MPEG Streamclip is just one MacOS X transcoding utility. There are others.

    Open MKV in quicktime pro
    wait for movie to load/buffer
    file - export 'mpg4'
    on video setting tab choose 'pass through'
    the only thing you re-compress is the audio, it is downed to stereo aac

    the mkv then becomes a mp4 with no loss in video, but loss in audio (if not botherered about 5.1 no big deal)
