Since installing Firefox 4 have had problems streaming video on from Hulu and comedy central, but problem goes away if using Explorer 8.
On Hulu will not play commercials (not that I care about this) but also freezes up from time to time. On Comedy Central could not access the list of episodes for Daily Show which are aggregated by week. The week labels show, but clicking on them does not bring up the show episode lists. Not a problem before loading 4, and switching to Explorer solved the problem. Are there known compatibility issues with video players?

The answer, changing McAfee firewall settings for Plugin Container for Firefox from "block" to "outgoing", worked for me. I have no idea why Firefox 3.17 works fine with Hulu without changing firewall settings but Firefox 4 fails.
