Hi, and welcome to LQ!
It's hard to guess what might have gone wrong, especially without a little more info. Could you kindly tell us which distro and program you are using to read the films, as well as the OS and program used to create them? It might also be helpful to know the copy software used in the transfer, and the file type/extension.
