DVD question

Feb 20, 2009 at 8:55 PM
It appears that a DVD has a UDF image, but merely copying the files does not create a disk that is playable in all DVD players.
Do you know what is the extra setting that makes a DVD playable on all players?
Also do you thing your Demo that creates a iso image from a dvd that will have that setting, so when you burn it, will it play?
