    Can anyone give me a link to somewhere that I can download some demuxing software. It's for my ipod. I've done a search on google but when I click on the sites, I don't really understand. So if any of you in the know could help, I would really appreciate it!

    Thanks

    in short, demuxing = single stream copying. Are you sure this is what you want? If so...

    virtualdubmod should do the trick for you. your video files have 2 streams, audio and video. What you're looking to do is copy the (for example) audio stream to a file, but ignore the video file. This is easy work for any video editing tool.

    Great. Thanks a mil. Yeah well basically when I play videos on my ipod, I can see them but I can't hear them. So I was told that this is what I should do! That's right isn't it?

    What are you using to encode the video with as it you should not have to be messing with demuxers to begin with in the first place.

    Yeah, the place to look is whatever you used to encode the videos. If you're trying to rescue a large number of encodes that you've already done, then fair enough, start looking into demuxing the video. Otherwise, I'd suggest trying to re-encode first. (edit: the sound not working is a symptom of an encode gone wrong)

    If you're trying to rescue, what you're looking to do is this (as I understand it, which I'm pretty confident is correct):

    demux the video from your existing ipod file to a new file.
    re-extract the audio from the original file (not ipod file) to a new file.
    mux (add together) the new audio and video files into a new file.
    try to play the new file.

    Doom 9 has some excellent howto's and introductions to video editing.

    Hope this helps.

    edit: virtualdubmod should be able to do all of these things, though it takes some getting used to (doom9 has a good howto). mencoder is a command line alternative (really useful for automation).
