Hello, I have been having a problem with reauthoring dvds with dvdshrink. When I reauthor just the main movie title my dvd player can play it but my dvdrom in my pc can't. it used to work all the time before. if I put it in my dvd-r rw dive it will play it also just not in my dvdrom drive it gives me a not reconized format error message. any help would be appreciated regards, taurus1
