I've been working with Hulu the last few days giving them details from the Thunderbolt phone. After ICS installed last week, my Hulu playback no longer worked. I'm glad to report that Hulu fixed this issue over the weekend. They had to tweak something on their end to accommodate the ICS update on the Thunderbolt. The update messed with some configurations required for proper playback. They put in a permanent fix for all HTC Thunderbolt's and all should now be well. Mine works just fine now. If you had this issue prior to the weekend, try again now. You may have to uninstall and reinstall Hulu, but it should work now.
