Hello all. Got a problem. When I click on the YouTube application and choose a video to watch, I get an error message saying that "This movie could not be played." But when I go to the YouTube website through Safari, I can watch videos, although they're much grainier. Also, others with an iPhone can watch videos with the YouTube application. So it's not a problem with the network. There seems to be something wrong with the app. Anybody got any ideas. Thanks in advance.
