I got the popup window, but no Play button as far as I could see. No autoplay, either, and I waited quite a long while. Well, quite a long while for me, at any rate. Still, I think it was enough time for something to happen.

I was indeed on a wireless connection, and I did see the low bandwidth link and clicked on it. Also with the "big nothing". I'll give it another shot when next I've got my laptop at my office so I can hook it into the cable. Desktops for work, laptops for work with occasional fun is my general rule of thumb, and it's avoided all but one crippling computer meltdown.
