Thanks Bob,
Tried all your suggestions but it still ain’t working.
Swapped cables, breakout cable, terminators, tried composite out of digi deck.
I still see ‘no video’ in the ref in on the AJA control panel.
Unfortunately despite the fact that we have multiple systems, they are of course all PCI-X, although I think there is a PCI-E intensity card floating around somewhere.
I was afraid there wasn’t going to be any simple solution and it will just be the usual game of testing and replacing every single component until I work out what the problem is.
Fun, fun, fun.
