Set your speed connection higher so it can accept both, thats what I just did, worked for me.
Go to that little arrow pointing down on the bottom of the webcam screen and click connection speed, choose a speed that works with you computer, I have cable but it was set to 56k
I bumped up the speed and I chekced the box to allow two vids at once and after a few seconds both cams refreshed and played at once. Hope that works, but you need a faster connection in the first place.
Anyone know where the shcedual for tonights games are?
