Judy, I couldn't find my copy of the compression program after I did a system restore the other week. Otherwise, I would have done it for you. You can download a trial version of 2 programs that are good for already created flash movies:
1. Sorenson Squeeze:

2. FlashOptimizer:

Hope it works! But hey, your av is already dancing!!!
