Clicking on an mp4 or compatible quicktime from mobile safari jumps into the Quicktime player, and it plays the audio, as well as the progress bar movie, but the video doesn't show (it's just the blank screen with the quicktime logo under it).
Rebooting the iphone lets it work again, but I can't figure out what's causing it to stop working.
