I just received the Media Adapter PlugIn for my iPhone 4 and I've played around with some of the features so far.
From what I've found, it has the beautiful iPod Out interface, and allows for video output as well. Unfortunately, the one video I did test did not show up. It only showed black and played the audio. Any thoughts?
