You can try using the "fscommand("exec", prgnamehere);"
method but I'm pretty sure that it won't work directly with a
filetype. It is mainly to open applications. Check the help files
for the exact syntax. You will have to place the .mov file in a
sub-folder named "fscommand". If this doesn't work you will have to
use a 3rd party software product like Northcode's SWFStudio
(www.northcode.com) or FlashJester's Jugglor (www.flashjester.com).
