Get a DVD RECORDER and forget the PC route.

Item 1 is DEAD ON ARRIVAL because you have the USB connection which the quality is so poor that I never unpack the USB cable and wonder why they give that to us. Connect with firewire, be happy.

Item 3 needs not much else other than "obvious items" such as software to make the DVD (DVDSanta?) and the DVD drive. And lots of time...
