Oh, by the way, there is another change to the video player that I hope is temporary. If you go to a channel page that is not webcasting (i.e., isn't "live"), the video player shows "Loading Channel data" and then gets stuck at "Loading Video". It appears to be an error, but it really isn't. The channel isn't live so there's no video to load. It's just confusing. I trust they will resolve this issue at some point and go back to showing the offline image when the channel isn't Live.
Update 12/20/2013: They did fix this.
