Ok, thanks for the info. I've had "partial" success in creating an ogg
video file from my QT movie. I did the following:

1. Downloaded XiphQT package from:
http://www.xiph.org/quicktime/download.html
2. Moved XiphQT.component to ~/Library/Components/
3. Loaded my doc-view.mov movie into iMovie
4. In iMovie, selected File/Share... menu option
5. Selected "Expert Settings" from the drop down menu
6. Selected "Movie to Ogg" as the Export: option and pressed
"Options..."
7. Under "Video Settings", I selected "Best" for Frames per Second and
"Best" for Compressor Quality and "High" for Sharpness

The movie was converted to OGG format (e.g. - an OGG container with
the sound in the Vorbis codec and the video in the Theora
code). However, although the resulting sound quality was ok, the video
quality was very poor. It was so poor that, although I could make out
what was happening in the movie, it is doubtful that anyone would want
to watch it. So, I guess converting .MOV movies to OGG format isn't
really a viable option.

On Mac OS X, I can use VLC to view OGG videos; however, I haven't been
able to find any screenrecording utility that will save to OGG. Does
anyone have any recommendations?
