What happenede to the movie?

[fak119]

On my Mac I have three movies (format .mp4) which I wanted to sync to my iPad. I managed to include them in iTunes on my device under the tab "Movies" but when syncing only two of them got transferred!
I repeated the process several times, no luck...
The three movie were downloaded from several TV channels and converted to the MPEG-4 format.
What might be the reason?

If its the same movie each time it could have a DRM .
You did check to make sure you had enough free space left to load it right?

There is enough space, but:
What is a DRM?

You didn't get an error when you tried to transfer? Are you certain the offending movie file is in the correct format? Can you play it in iTunes or QuickTime?

As osxx says, if the file is copy protected it won't copy over.
