I believe Adblock Plus will cause Hulu movies to skip over the commercials, except for the first one (which gives you a 90-second "please turn off your adblocker" message) but I cannot be sure, it has been a while since I last saw anything on Hulu and judging by how much they play around with it, they must spend more money on anti-Adblock Plus technology than they do on buying the rights to content.
