Hi
This little piece of info will only serve as a reference. I made a copy of my 'Force 10 from Navarone' movie, written to a media called Princo. Probably unavailable in your kneck of the woods. I also have two DVD players, named 'C-Tech' and 'Digitor'. These two products are also probably unknown to you. The copy plays jerky in the Digitor player, but runs perfectly in the C-Tech.
Trust this may help in some way
