Pinnacle dvd won't play

hello All,
I edited my friend’s video in Pinnacle Studio 12 Ultimate but it plays for a few minutes and stops. I have uninstalled and installed but no joy. My Pc is intel core 2 quad. Can anybody help please?

Obviously something has gone wrong in the editing process. First thing I would try would be to run the dvd through FixVTS and see if that helps.
