I've been enjoying Air Video for years now and I happily upgraded to Air Video HD when it came out.
However recently my air video kept crashing within a few seconds of playing. Rebooting both the air video server and the app doesn't resolve the problem.
The problem starts with initially streaming to the apple tv, then stopping the stream and redirecting the output back to the iPhone or iPad.
While still on the same video, redirecting it back to the Apple TV will cause the video to drop and crash. Sometimes skipping to the next video.
select a different video then go back to the problem video.
