Movie Creator in Nokia N70

Hi. I just wondered if anyone has been able to sucessfully use the
Movie Director Application sucessfully to create a basic movie theme
for sending via MMS?

When I select the video and theme, and then select multimedia message
as the size, it never seems to save it properly. It gets to the last
second on the countdown and then freezes.

When I click cancel after waiting a while the movie is there but it
freezes just a couple of seconds from the end on playback, and it is
always slightly over the 100kb size for sending to another mobile.

What gives? Is this a known issue with this application on the Nokia
N70?

All the other options create a movie that is much bigger in size so
they are no good either.

Thanks for any help on this

John
