I downloaded a movie, and the format is .mp4 I though the iphone i would play the mp4. That was a no go. I was unable to play it with quick time. I tried to get a s/n to register it as quick time pro. But that didnt work either. Got some bad s/n from waffles. My question is, how can i get this to play without using VLC? Is there a converter that every one likes to use due to its simplicity?
