I signed up for Hulu in order to watch that... but I guess I don't have a fast enough connection speed. It wanders from "slow" to "very good" and "excellent", those connection speeds ... and you take what they give you.
I have a dial-up connection myself. If you pause it and let it buffer all the way- like go do something else and come back to it in ten minutes-the videos usually run pretty smooth for me.
