Maybe this could help in some way.
I just completed a project...I don't have video in mine, but I needed to create a version for both Mac and PC.
I used CDEveryWhere to make it possible. When you publish your .fla to a Mac projector, it saves it as an ".hqx" file. That file has to be decompressed before you burn it onto a CD or use in a Mac. Yes you could send it to your buddy with a Mac and they could decompress it for you, but that is messy.
Here is the thread with all the info needed.

Sorry I am not up on the video part of the question, but hope this helps in some way.
