Well, nonetheless this method does make previously unplayable PAL content work in North American DVD players, whether or not the content is actually converted or not. And it remains playable in every machine I've tried, with no loss of quality, sync or menu problems at all.
It may surprise you all but after googling and searching for a simple solution without success and without a laborious conversion process using multiple software programs...
IMGBurn creates compatible DVDs between PAL and NTSC and thats what I need, as have many others in many forums. And its so simple.
