Just because something is not thread safe does not mean you can not
run it in a separate thread. The issue with thread safety is to do
with things being accessed from more than one thread. As long as all
the communication with the Movie Expoer component always happens from
the same single thread you should be OK.

It would be nice if that was true, but it isn't always the case, for
example if the non thread safe api is accessing some global data that
belongs to the system (and accessed by other threads without you being
able to do anything about it).
