Video FX Green Box

Hi,
I'm completely new to multiboxing and just watched Mirai's healing video. While trying to do the source and viewer in video fx I can't seem to get it to work. All I get is the green on the viewer and no source. I've tried it several times and still nothing has changed. Please help.

Whether VideoFX works or not comes down to literally 3 things:

• The source and viewer have IDENTICAL names
• Windows Aero (Windows DWM) is enabled (Windows Vista/7/8 all have this)
• You're not trying to do this across multiple computers

If you don't know how to enable Aero on Vista or 7, then you should consult Google. Also, if you've got the in-game GUI open, then you're going to see the "green box" until you either close the GUI or hold the CTRL button (as stated on the green box itself).
