Removing Camera Drivers?

[ROYALEFATALE]

when in flash settings/isight selection, i have a huge dropdown list of 'cameras' most of which aren't cameras such as DVC PRO HD x 4, DV Video, IIDC Firewire Video, Google Camera Adapter 1 and 0, all of which i'd like to delete, some websites have glitches where the entire list isn't accessible, which means i can't actually select my USB Video/iSight at the end of the list, anyone know where the drivers for these devices are located or how to remove them from my list of cameras/devices? thanks
