Dvd Stops

[tillitea]

I recently backed up a DVD that was double- layered onto a DVD-R by taking out extras and language streams. Everything works perfectly except for one little thing. There is one part towards the end of the movie where the movie stops and then starts over from the beginning. I have my own theories, but might anyone know why this may have occurred?

Side Note:
This is not the case in this situation, but if the original DVD does this stopping thing and I make a backup of it, will the backup stop at that spot too? Thanks

It would be beneficial if you'd indicate what software and procedures you've used...
