I am trying to disable my Isight on a couple of computers used at our library. Under MacHints I found out that, when a program from OS X (Tiger at least) needs to access the integrated iSight camera, it has to call the QuickTimeUSBVDCDIgitizer.component. This file is located in the /System » Library » QuickTime folder. How can I find this folder? When I search for it does not come up. Or did anybody else figure out a way to disable this. Oh, yeah, taping over it is a good suggestion but clever people just removed. Thanks.
