The video isn't much help(to me anyway). Here is how I would troubleshoot:
1-Assuming all was fine with the older 192, disconnect it and connect the newer 192 alone and test all the IO.
2-if that tested bad, return it for a refund
3-if it tested good, the reconnect the second 192 and triple-check all the connections.
Not knowing your experience level on this, This info may be old-hat....but check these things:
1-loop sync(BNC cables must be in place, correct and solid)
2-if things are not working with 192 #2 connected the the Expansion port of 192 #1, try connecting #2 directly to your card(which you failed to mention at all)
