Trying to make a Blu-Ray with multiple selectable camera angles. When I go to insert an extra video track in the main timeline, my project size immediately doubles. Anyone know why this happens (and how to make it not?). Then when I try to add in the extra video stream, it doubles the size of that stream as well. Making it virtually impossible to get a second (not to mention 3rd) angle in without lowering the bit-rate to something super low. Ideas?
