I've posted the message but thought i lost Your precious answers, yet i didn't find it in archive too, so, i'll try to repeat again my questions on this subject. I want to edit a DVD movie (video and sound) yet let's look on it in two ways: a) video and sound; b) sound only, if it helps to save quality somehow. So, How to make it the best (the easiest)? Probably i need to unpack > edit > pack DVD again. - By what. Is there a way to spare quality if i edit one sound track only? Can i delete a track? Thank You for participation! - It's a big deal to me! -- Best regards, Strong.
