There shouldn't be any problem dealing with files this large from
MC/RR, but I'd recommend not crossing that boundary as a matter of
sanity: there are just too many thing that can go wrong with files
when you cross the long-integer (32 bits - 1 bit for sign) boundary to
make this a viable development plan. Better to just split the movie
into more managable chunks and change the fileName property of the
player as needed to show the appropriate chunk.

No, there is no built-in support for creating QT movies (or even
adding to them). Worse, in your case, there isn't even any way to
access the information in a time code track from the player object.
This is a job for an external. Note that you can continue to use the
player object if you prefer, using the movieControllerID property to
access the internal data structures the external would need to deal
with the movie directly.

Hope you have better luck there than we have ;-)
