Some others have mentioned the alwaysBuffer property.  You can also use 
LiveStage and accomplish what you want.  If you have access to 
Livestage Pro you can create the captioning in text tracks (LSP has a 
Media Synchronizer that might help) and then create links that within 
the text that call the DebugStr function.  Revolution can trap DebugStr 
(QTDebugStr player message) messages from a QT movie and respond 
accordingly.  I use this with QTVR and it works great.

Keeping the captioning with the movie can be beneficial if you end up 
deploying the movie on the web as well.
