ABC's Enhanced TV will be running during the show.
Also, additional video clips will be available through ABC Motion. New Mole content will be out Tuesday, Wednesday, and Thursday. After you've downloaded the player (broadband Internet highly recommended) and given it some time to download content (it downloads videos on your computer in the background while you're connected to the Internet) you can view the videos at abc.go.com.
I also found out that they are saved on your computer in Windows XP at:
C:\Documents and Settings\All Users\Application Data\DIGStream\ABCMotion
When Mole content comes in, you may wish to copy the videos to another place to save them, since the ABC Motion does delete old content.
If you don't have any programs which will play WMV files, get Winamp.
