Hi mpersico and welcome to cdfreaks,
Not sure of your settings and how you set your burn up, but for starters, try this:
> Open Fab
> Click on [B]Write Data[/B] (left hand column under DVD to DVD).
> Click on the .ISO icon to the far right of [B]Source[/B] (looks like a dog-eared page with a disc overlay).
> Navigate to the[B] .ini [/B]file of the selected movie and choose this as [B]Source[/B].
Now try burning the flick.
Hope this helps
