I'm working on DETROIT ROCK CITY. The movie only vobs are 3.0gigs. I want to add the Detroit Rock City music video and the section on how to play 'rock and roll all nite" on guitar. I'm using DVDshrink. Do i use DVDshrink on the 3 different vob sets and save them in different folders then add them all to one folder then once again use dvdshrink to resize? thanks
