Ok, burned about 20 dvd'd using shrink and nero and feeling pretty good about it thanx to all the help in here! I'm ready for the next step - Reauthoring. Is there a good guide that explains this? I can do it in shrink right? Which files do I actually need? vob? ifo? bup? I have no idea what the purpose of each of these files is. [bold]Also,[/bold] what's the difference between the different sound files on the dvd? Like 'AC3 ch-6' and 'AC3 ch-2'. Or sometimes even the 'AC3' part is different. All of your help is greatly appreciated! Thanx.
