I've captured material from my DV NTSC widescreen camcorder, and assembled it together. When I render the product, the segments start and end at slightly wrong places. I really can't figure out why. The project is configured correctly at DV NTSC widescreen, and everything plays perfectly within the editor itself.
One hint may be that the final rendered product ends up at 25fps while the originals are all 29.97 fps. Is there a way to force a framerate in the rendered product?
