Sample description: The multistory demo is done with a section of video that's seamlessly connected to another section with three angle blocks. You set the angle in a menu, then when it hits the transition as it plays it seamlessly selects one of the three angles. The main problem is that each angle block has to be the same length. In my case one segment was shorter than the other two. We got around that by breaking the angle blocks into chunks and putting a post command in the short one to jump out when it's finished playing. (So itís physically the same length as the other two angles, but you never see it play the black video at the end.)
