Hi. I've put together what I believe to be a very polished DVD, save for one thing: multiple audio tracks. Frankly, I have NO idea how to use them, and my (admittedly short) expirments have not proven to be very fruitful. If anyone could give me a quick little runthrough on how to use them effectively (I have four different video tracks, each with two audio tracks) I would be ETERNALLY GRATEFUL. This DVD has been put on hold too long! I am using Beta 10 of DVD-Lab Pro. Thanks in advance!
