Now - how do i get milkdrop to actually play in the window with winamp?
Not sure at what point of the setup you are now but here is a quick checklist:
1)Install Milkdrop plugin (I'm using version 1.04)
2)Configure the Milkdrop plugin - In the Common Settings tab, under Windowed settings, make sure that the option "integrate with winamp" is uncheck (this is important). If you have a slow pc or graphics card, you can also check "Allow page tearing".
3)Setup your page where you want to show the visualization window by:
a] creating a text box using "plugin>XMoveWindow>MilkDrop"
b] on the ID for that text box, enter "name of your screen_MilkDrop"
c] create a button using the "start visualization" event. (found under the
music command.
*Visualization can be turned off by sending the same event. Also, if you notice on a and b above, I'm using the name Milkdrop because that is the classname that is showing on my system. If it doesn't work, use Girder or another program to find out what classname Milkdrop is using on your system.
Hope this helps. Let us know how it turns out.
