How to get a movie I made from computer to iphone?

So I made a video with windows movie maker and I added a song to it but I can't upload it to youtube because of copyright issues. I just want to share the video with my friends so how do I show them? I've tried uploading to Facebook and that didn't work. I can't e-mail it to myself.

Without looking at the error messages I would imagine that it's a software incompatibility issue. If you made the video using MS software (windows) then you iphone (which isn't MS windows) would not be able to read the video on your phone using the software on your phone. You would need to convert the video file using file conversion software on your PC first (you can download such software off the internet) into a file type that can be read by your iphone. You will also be able to get help on how to do this by googling the question.

What do you mean "can't email it to myself"? Of course you can. As a general rule, email attachments can be of any form of digital information (text, images, sound, video, computer binary code, telemetry data, etc). The device has no possible way of "knowing" who owns the data or the right to distribute it.
