Flash movie while downloading

Hi, I'm kind of new to NSIS but what I'm trying to accomplish is play a flash movie while downloading content for the install. I am able to use the nsisdl plugin to download content no problem, and I am able to play a Flash movie using the nsWeb plugin... However the problem is that the while the flash movie is playing, the downloader is paused... Even if I try to play the movie in a pop up window.. It resumes upon closing the flash movie out.. Is there a way to make NSIS execute a command and then keep going and execute the next command?

Or maybe a better way to phrase the question: Is there a way to execute a plugin command and not have to wait for it to finish, similiar to calling Exec, only for a plugin function instead of a command line program?

It's possible. Take a look at the Banner and BgImage plug-ins for example.
