HowTo embed multiple video separately?

I have created ten swf containing flv video. When I embed them through code in my main swf using FlashDevelop I get only one video stream. All my videos that have the same frame size (width x height) are embedded as a single video stream.

I’ve noticed that only if I have a video with different frame size (width2 x height2) then it is embedded separately.

How can I force FlashDevelop to embed all videos separately?
