I am running 4 cams off of a 12 cam dvr, plug in video capture device so I can stream to Marestare, but its showing me all 12 cams, ones not in use say Lorex in box,
how do I get rid of those and just make a quad scree, already changed in Lorex tabs so, on laptop its show 4, and on tv shows 4..but adobe flash shows all 12 !!
