I have an old GV600 card that has been happily recording three cameras at 640x430 on a Pentium III system for over 5 years. I had to upgrade the PC to a Pentium IV system, installed the new Geovision 8.4 software and now can only get 320x240, even when I set the Video Source attributes to 640x480.
Why, and how do i fix it? Ta!
