I'm also having the slow loading problem. It was fine before, but I think it's been around for about a month now. I haven't been checking that often, but now it takes about 2 times the video length to load it, in low quality.

Ironically, downloading the video via the button works at blazing fast speeds (300-400KB/sec) so I don't know why your video player won't work that fast for me :(

The site otherwise shows no signs of hiccups. East Coast, by the way.
