Could be something with keeping the Theater Mode syncron.
My question is how does anyone know if there the Host? Is there a box somewhere on screen telling you that "your host" or w/e...I always wanted to figure that out.
Watch for awaiting challenge 0 and then tap back as soon as it loads until you can see the connection bars. If you're the only one with green bars you're host. If it goes from awaiting challenge to awaiting connection 1,2 etc you're probs not host.
