I embedded the custom YouTube player so that I could include a bunch of our vids. But can't for the life of me get the thing to center. I found code for centering it, which I will paste here for you to see. Let me know what I am doing wrong.

Also, the player doesn't seem to accurately scale to the edges of the block. Block is 700px and the viewer skips around from too small to too big when I make incremental changes to the size parameters.
