Has anybody already found a solution to this problem? We are looking to get iChatAV running on a G4 desktop and need a webcam and mic. I have done a bit of research and found that ideally, a Mac external iSight camera w/ built-in mic is the way to go. Problem is that camera was discontinued. I've read that ideally you need a camera that hooks up via firewire but any USB camera should do if you get the iChatUSBCam software for $9.95. Then, you need a mic that hooks up via USB. Well, can anyone give me manufacturers & exact model numbers of firewire cameras and USB mics they have had success with on OSX? It seems to be a real problem, esp. since all Macs now are coming w/ the gear built in and the demand is lessening.
