So here's a really weird problem I'm having: I have several timelines in a DVD project that, from the menu, can either be played individually or all at once. All of the individual playbacks work fine; the problem comes when the viewer selects "Play All." The first three clips (out of about eight) play fine, and then it kicks back to the menu. I've checked all of the end actions for all the timelines and they are all correct. Any ideas as to why this might happen?
