I have a weird problem that I can't seem to track down.
When playing back a DVD I authored and burned, there is one segment when played back on a Mac or PC DVD player that the audio increases in volume on its own. The segment starts very soft and in about 15 seconds ramps to being very loud. This does not happen on a stand alone DVD player. The problem was bigger at first. I had 5 segments that did this. I re-encoded them and all but this one was fixed. Every element on the DVD is encoded the same. I have a First Play, a Main menu, with 3 buttons/links to segments and 2 Submenus with 6 and 3 buttons/links to segments.

I have re-burned the disc image about 8 times after re-encoding that segment as many.
