The program works as advertised. I had none of the issues mentioned by the previous poster, it must be related to an issue with his/her system configuration.
I watch a lot of TV material on my laptop and was hoping to use this app to listen to the audio with my headphones plugged into my iPhone instead of the laptop. It works, but for video viewing, the audio is out of sync. This is to much of a distraction while watching something, so they can't be used well for that purpose. Nice idea, needs a little refinement to get the audio for video stuff to be in sync.
