Dissolves

Broadcast 2000 contains features to very quickly insert dissolves between two scenes. In Broadcast 2000 you paste the two scenes next to each other so you have a timeline like this:

Then you select the region between the two edits

Select Video->feather edits to commence the dissolve operation. This asks you for a number of frames to extend the dissolve. With the number of frames entered, you now get a dissolve when you play the selection. To remove the dissolve go back to Video->feather edits and enter 0 for the frame duration.

The Feather edits operation is identical to if you created the following timeline. Here the bottom scene faded out after the top scene began.
