I’m running iOS 4.4.3 (3323) 5.0.1 (9A405l) jailbroken with the latest Seas0npass (0.3.44.3702). Nothing works under the Internet tab except Netflix. All video content (YouTube, WSJ, etc.) shows the spinning working icon when a video is selected. However, Netflix works fine so it’s not a connection problem. All local content plays fine as well when Media Player is installed. This behavior is present after a clean restore jailbreak BEFORE aTVflash black 1.1 is even installed. I get the same results after aTVflash is installed. I have rejailbroken multiple times with the same outcome.
I’m starting to think this has something to do with all the AirPlay problems people have been reporting for the last month and a half (http://forum.firecore.com/topic/5709), myself included. Mirroring works fine with my iPad 2, but any stock Apple apps (YouTube, Trailers) exhibit the same working icon and never play when attempting to use AirPlay. Third party iPad apps with AirPlay such as inMethod’s Air Video work fine. The AirPlay interface for Air Video looks a little different than Apple’s, so maybe they are using a different framework.
