Thanks for everyones posts.
Something you all should know is that we always ensure the Video PPU and and the Catalyst servers are on the same supply, I am a qualified electrician and I am fully aware of Potential Difference created between 2 different power supplies and the damage it can cause.
I would like Active Silicone to be more proactive in getting to the bottom of this with us. They know that we have 5 servers with 2 cards in each.
For the record.... a rogue machine has to be ruled out as we have suffered failures on a number of the machines.
I agree that opto isolation would help the cause in insuring a voltage free ground, but I'm sure in this case we have other issues. XL video are looking into this, but of course they see this as protecting someone else's kit.
How do we explain the intermittent comings and goings of the card and driver recognition for example. How come the Decklink HD3 worked straight from the box with no change of mains powers supply, and therefor the same possible potential difference as suffered by the AS cards, are they more hardy to it?
Whatever the resolution from AS, there hardware must be as durable as that from Kona or Decklink, we all agree on this right? I know that there is some flakiness with drivers sometimes from both of these manufacturers....
Thanks again for everyones input.
