Preview
One issue you may have had while you were performing the AutoLive part of this tutorial is that you could not see the changes you were making.
AutoLive was off, so the changes weren't Live. And you could only see Live.
To alleviate this problem, Wirecast allows you to see a Preview of what will go Live.
Press the "Preview" button on the top right of the main window (or select "Preview" from the "Layout" menu):
Your main window should now look like this:
The Left side that has the small green square with a "P" in it is the Preview area. The Right side is the "Live Broadcast" area.
On the bottom left of the window, turn off the Foreground and Title layers by clicking on the 
icon and the 
icon.
A little red X will appear over those icons and you window should now look like this:
Notice how the Preview (left side), shows the changes you have made (you have hidden the Foreground and Title layers).
The Live area still looks as it originally did.
Now press the "Go" button.
The Preview is taken Live, using the transition that you have selected.
