Deleted but virtual cameras still show

I installed ManyCam on my MacBook Pro, and for several reasons it would be more useful to me on a different machine. I clicked the “uninstall” icon and it appeared to run okay, but when I launch a video-aware application I still see my two Manycam virtual cameras, and one of them is the default.

Besides running the uninstaller, I checked for:

~/ManyCam
/Applications/ManyCam.app
/Library/QuickTime/ManyCamVDig.component
/System/Library/Extensions/ManyCamDriver.kext

… and foud none of them.

Please advise?

thank you
