The built in feature in settings to disable commercials fixes the problem BUT I'm hoping that they correct this as I am a firm believer in Hulu's right to make money from commercials for offering me these shows. That being said, Hulu needs to pull it together and help make their stuff work on different platforms so that they can financially gain from Linux and other users watching their shows.
Did you disable commercials? Would explain why it works so well for you, if not try the shows that I listed, my guess is that they will start and then cut out about 10 seconds in (like I said, disabling commercials apparently fixes this).
Also I've found that subtitles don't work, already requesting this from bluecop, that developer deserves some donations from anyone using it, it's a great addition to XBMC
