Angel Season 2 Episode 21

Angel, 43, Through the Looking Glass

I've watched the whole series on this site up until now, and haven't had a problem yet. I try to watch this episode, and, regardless of how much of the episode it says has loaded already by the graying of the bar at the bottom, it stops about every 3 seconds and comes up with the swirling circle in the middle of the screen, resuming after about 10 seconds. I paused it at the beginning to let the whole episode load first, reset my airport, restarted my computer, and they were no help. The only way I can possibly watch is in 3 second intervals.
