Rendering problem.

Hi guys. I have one small (or big) rendering problem with sony vegas . So i want to explain first how i do (not the settings but the sequence of putting the parts) . First i make intro in AE (23 fps) and render it than i put that in vegas and than the jumps , edit them,outro . So the problem is when i render it i canot see the intro and some parts of the movie are like u know when u watch DVD movie and it will stop for a second the screen will be with all colors and for about 2 seconds it will disappear and go on with the movie . The quality is perfect but :( some help,someone experienced this and want to share how he fixed this ? Ty in advice
