Hi Henri,
About closed captioning and quicktime
Built-in solutions
Solutions such as QuickTime Text Track provide closed captioning,
while iChat AV and iSight provide the first video conferencing
solution with strong enough clarity to allow sign language
communication over the Internet. With these built-in accessibility
features, Macs enhance teaching and learning for a person who is
deaf or hard of hearing.

It doesn't give that much info, exploring further, I found
* Text Tracks
http://www.apple.com/quicktime/tutorials/texttracks.html
* Text Descriptors
http://www.apple.com/quicktime/tutorials/textdescriptors.html
Here something captioned with SMIL. (tested positively in Camino and
Safari 3).

I found also movies in Itunes which were done with Text Track and its
working in Safari 3.1 and Camino. Example. It was on by default and I
didn't find anyway to remove it in the browser.
