Video capture not working

Hypersnap version 6.90
Windows XP SP3 x86
 
I have enabled the:
Video Capture (Media Players, DVD, etc.)
Game Capture
Games from 3dfx Glide Controller (not available)
I have also enabled Post Processing of pictures snapped from games
With 3D Graphic controller unknown
I enabled the Hotkey:
Ctrl + Shift + ~ (because my laptop has no scroll lock key)
 
Still with all that, I am unable to capture a still shot from Windows Media Player 11
Am I doing something wrong? I can't figure it out!?!
