Additionally, you can check the codec information to see what the difference is between one that plays and one that doesn't.
I think Apple is kinda strict which what formats it supports, if its not exactly right. All it takes it an audio/video codec issue and it won't play regarless if its the correct format..

.mp4 is only a container... VLC will play just about anything.
