[iTunes] movie help

[Terry Pogue]

I gave my friend an apple computer that's about 5 old to watch movies on. I had a movie I had watched on tv that she wanted to see so I burned the movie to disk, then ran Handbreak on it and walked her thru how to load it into the iTunes library. I wiped my account off that computer and set her up giving her Administration over it. The movie loaded fine but it won't play. It first said that the computer wasn't authorized so I found that under advanced. Then it wanted my itunes store name and password. She plugged that in. She is not connected to the internet on that computer. It seems to assume she bought this disk from the iTunes store or something. How do you get a regular old mp4 movie to play on iTunes? Surely you can use iTunes without  with store involved??
Thanks so much,
