    I have some videos on my iPhone that when I email them to someone they open in QuickTime. It acts like it's playing (the bar and time are moving), but there is no actual video or sound....

    Any suggestions?

    Sounds like problem at the other end. Macs or PCs?

    which OS X version is this? I know the quicktime on mavericks was always terribly buggy and they never fixed it

    The one I'm on now is Lion. I save/download from email as a .MOV file and it opens in QuickTime, but can't see or hear anything.

    QuickTime is just a wrapper, not a codec and it sounds like the computers you are trying to play the MOV on don't have the proper codec. When you open the file in QT hit command+I and where it says "Format" it will tell you the name of the codec.

    You can think of a wrapper as kind of link an envelope and the codec as the language used to write the letter contained inside the envelope. If someone sends me a letter I know how to open the envelope but if the message is written in a language I don't know I won't be able to read it. That's basically what's happening here.

    Same problem in QT

    Ever since Snow Leopard, I think, double clicking a QT playable file only opens a blank window but nothing happens. However if I drag the file to the QT player icon, it opens and plays just fine.
