The UScreenCapture installer "adds" some registry values. ffmpeg then makes a call into the directshow framework, which returns the list.

run regedit and search for "uscreencapture" that's all I can suggest, since I don't know the details.
Basically it sets itself up as a directshow device, and lists the path to uscreencapture.dll or whatever file their dll is.
If you're looking for registry settings to "control" where it captures, you'll have to look in their documentation.
