Allow full size

I just installed this module, and I'm happy that it was so easy to set up. I spent hours working on the video module, and just couldn't get it to work for me.

But, I do have a problem - I would like my users to be able to use the full-size button on the video player so they can see the videos in full screen, but the button doesn't work.

I believe the flashvars allowFullSize = on (or something like that) has to be set, but I don't know where to set it.

If I am just missing it, can you point me at it? Or if it's missing, could you add it into the next release? Thank you.
