QT sucks. Youtube (Flash) sucks.

People usually recommend ffmpegX for OSX. You might give it a whirl to
transcode your mov to something else, let's say H.264 in an AVI
container. (MP4/AVC, DivX, xvid, there are so many names for it)

You can also create flv (flash video) and use one of the free
flv-Players to achieve some kind of Youtube (i.e. playing right in the
browser), just without the 10minutes limitation.

There's also the SMIL format. It allows to reference some images (your
slides), the timing between them and your audio stream. It's like
composing your presentation, though some sophisticated products exist
to capture video, the slides, additional material and notes written by
hand on a digital screen.

But I guess it's too complicated for your purpose.

It's just because QT sucks. And the data streams are proprietary (very
big concern).

PS: My private list of sophisticated players: mplayer, VLC, xine.
    Braindead players: realplayer, QT, Windows Media Player
