      Some of choose to use .mov files compressed with H.264 because of
      the potential to add hyperlinks in a .mov file. To lose that
      functionality is a big bummer. AND to find this out after lashing
      out and buying QT7 for Windows is even worse!

      If you would be so kind, please double-check as to whether it's
      true. The latest post at Crash Test Kitchen is a .mov file
      compressed using H.264 and if you're right it won't work on your

        Hey Steve: What you are saying to me is that you simply changed the
        extension from .mov to .mp4 and it worked on the iPod? I'm confused.
        Because I did not do the export to .mp4, selecting the "baseline"
        thing that Michael described. Rather, I made a DVNTSC 640x480 movie
        from the original DV movie. I then exported it Movie to iPod
        (320x240), and simply changed the extension from .m4v to .mov. It
        should have that "main" profile. But since you say it plays on your
        iPod, I'll go ahead and change the extension to .mp4 and upload the
        video to the server again.

        Thanks for you help.
