When I add, remove or change cams I get a lot of problems as described in some previous posts.
The audio and video sources are mixed and none or just one cam works.
In the iCamSource preferences window every source (audio and video) is identified by a number followed by the source description.
es. Audio 1 - Logitech...
I noticed that when the number is the same for audio and video for the same cam all is ok. But this happens randomly.
When I have for example:
Audio 1 - Logitech, Video 2 - Logitech, Audio 2 - iSight, Video 1 - iSight and try to set the correct sources in the preferences window, none or just one cam works.
I deleted the iCamSources preferences in the Library and start over again but I get the same problems again until (randomly I suppose) I got the number in the correct order. Then closing the preferences window, quitting the application and start again all works fine.
