Are you hoping to have both cameras displaying their images at all times? Or, are they meant to do things at different times?

A lot of the problems you'll run into with cameras relate to the maximum bandwidth you're allowed to use during a match. As you saw here, reducing the image size allowed both to send. You can look at ways to play with the fps and resolution to help with this. You can also consider turning cameras on and off as needed so that you're not sending images and using that precious bandwidth when you're not planning to look at that camera (for example, if you have one camera on each side and a different view of "front of the robot" during different phases of your game)
