If you want to make DVD for North America you have to use NTSC setup otherwise they will not play on dvd players here. Most European players can play both formats, not in America.

I think you are stuck with it. If your computer does not see it, it has to be a bad disk. Maybe if you go back to the guy and ask for new disk in exchange, he may go for it, instead of refund.
I would take the disk with you and ask him to play it on his machine, see what happen.
