Since you also wrote luvcview, do you know what is going on there? When I start it I gert a black screen, and I see no controls, but I can use them. When I close luvcview, the console shows "Stop asked". Then it hangs. Ctrl-C does not work. Only killing the process or unlugging the cam works. When I unplug it, it says: Unable to dequeue buffer (5). Error grabbing Clean Up done Quit Does that give any hits? > You should post a message to the quickcamteam.net forums.
