Step 1:
Download the software, extract the files and start the wtvClient.exe.

Step 2:
Enter the address or hostname of the server in the left input control ("games.waaaghtv.com") and press connect. optional:
- enter the port in the right form if a nonstandard port 10383 is used.
- set your username in the input control on the right. Your last battle.net login name is used otherwise.
After the connection has succeeded, there should be games in the Games tab.

Step 3:
You should now see the latest games on the server in your client.
All the games in the gamelist which have the light blue background, will appear in your WarCraft 3 LAN-screen (games which are live, should automatically be subscribed).
Doubleclick on a game to subscribe/unsubscribe it. If you want all the games to appear in your LAN-screen, check the "Show all Games in Warcraft" checkbox above.
To view a game start "Warcraft III: Reign of Chaos" or "The Frozen Throne" (depending on what kind of game you want to see, check version in the client gamelist) and click the "Local Area Network" button.
After a few seconds, all the games you subscribed (and all the live games, if you haven't unsubscribed them) should appear. Select one and press join game to enter the game.

Step 4:

Just read the instructions in the chatroom to start the game.

How to synchronise the Waaagh!TV game with the shoutcast
It is now much easier to synchronise the game with the shoutcast, but the shoutcaster has to give you the time in his game.
Assuming the shoutcaster says that it's 13:00 o'clock in his/her game, all you have to do is to type in "/sync 13:00". Waaagh!TV will then try to fast forward to this point (or pause the game), so that you are exactly at the same point like the shoutcaster.
There is one known issue: If a player in the game has used a moonstone, Waaagh!TV isn't able to detect the time in your game, but you can "tell" Waaagh!TV the current daytime. If it is 14:30 in your game, type in "/setsync 14:30". After that you can use the method described above to synchronise your game (with /sync).
