On MacOS it depends from QuickTime, on Windows I don't know (perhaps 
try QuickTime).
On Linux I don't know either, probably it depends from the installed 
multimedia extensions (isn't there also QuickTime for Linux?).

Perhaps look for QuickTime docs at Apple.

You can't include them, you can only link to them (as like movies); I 
heard you could include media files since PDF 1.5 (Acrobat 6), but 
never tried.
AFAIK all multimedia extensions work only with Acrobat (Reader) and not 
with any other PDF viewer.

Adobe changed Acrobat's JavaScript implementation several times. And it 
has/had different bugs/features in every edition.
Acrobat 4 e.g. had a wrong or undefined state of some variables at 
startup...
Some things are rather strange: I tried to access user's settings (like 
measure unit), but that's not possible, at least in Acrobat 5.

5.0.9 is rather new and fixes some bugs of previous versions (on Mac 
and Win there was only 5.0.5),
but they don't seem to plan an Adobe Reader 6 for Linux.
But there is a Distiller 6 Server for Linux. I guess they see Linux 
mainly as a server platform.

There's no document I know of that gives a good introduction into 
JavaScript for Acrobat. You should know JavaScript "for Web" to 
understand Adobe's docs.
I started writing some simple extensions for Acrobat 5 some weeks ago 
and didn't find much what I could use.
Perhaps look at these:
