I have always used DVD-Lab Pro for my Authoring because it is a wonderful program. Now, after a long time using it I have the need to add subs, but I have one problem. The sample of the movie in DVD-Lab has no sound so I have to use an external player, compare the time with DVD-Lab's and then using the Subs creator of DVD-Lab make the subs. My question is: Is there a way to give audio to the sample of DVD-Lab so that I won't need an external player, but do all the work with DVD-Lab?
