I really don't think that an autoplay option is a good idea. Spammers will make use of it to instantly spam the browser window with useless popups. They now can just swap the file once it passed judgement.
Also I hate auto play. I want to decide myself when the flash should start.
It really isn't that good if a big flash (like the street fighter collab for example) that takes ages to load (hey, internet in Europe isn't that fast!). Now I have to sit the whole loading bar to watch a big flash from the beginning. If I just go away and let the flash load then I might miss the beginning of it.
Also also, the pop up button doesn't seem to work in Opera. Nothing happens when I press it. The other buttons work fine, though.
To the layout itself: Well, it's different. I like that now the flash is so prominent on the page. Not the author, not the authors comments but the flash. That way people might just vote according to the quality of the flash and not look at the author, thinking "I don't like him -> 0!" or "a flash by clock crew will just pass no matter what I vote -> 5".
But it will take quite some time before I get used to it...
