QT won't "Make movie self-contained" in OS X


I'm trying to create a QT Media Skin which requires that after you have compiled all the elements into a single movie that you "Save as..." and use the option to "Make movie self-contained".

For some reason, when I try to do this in OS X, the option is grayed out and all I can do is save with dependencies. If I re-boot and follow the EXACT same steps in OS 9, no problem.

Has anybody else had this problem?

I tried it using QT in Classic and it worked there too, just not in OS X (at least I don't have to re-boot!)
