I have a security system set up in my office with 8 cameras (channels) that feed into my recorder. I am trying to export or record some activity that I need to save from my surveilence and I either am not doing it correctly because the disk cannot be read by my Mac or PC computer. I'm not sure my settings are correct for export and I cannot locate my book. Time is of the essence. I need your help in recording . Thank you. RMGillis14@aol.com
