One is W7, the other Vista, but I'm sorted. Through sheer blind trial and error and many wasted hours, it emerged that when my Vaio was upgraded to W7, it didn't take the video drivers across so they were not fully enabled. It's working now, no thanks to the hardware or software for communicating in any way at all.
In a few weeks the cctv system's dvr will be swapped over for one which doesn't rely on ActiveX for communication with the outside world, at which point I won't be stuck with having to use the damn Vaio PC anymore and can use my MacBook andiPhone instead. Cant wait.
