How do I center my template?

[pixelz]

I have made a site (sadly hosted by a free host, I'm not one to purchase things over the net, although it may change) where I make flash games and movies. However if you notice the flash are not centered and look rather awkward slightly to the left. I'm wondering how can I center my template so it is always in the center no matter what size of PC screen.

sites which are centered in that fashion.

If there is not an option may I suggest a button that will center objects perfectly and it codes it so they remain in that positino, I've tried HTML but a simpler method would be fantastic.
