So I thought I posted this last night, but apparently not, since I can't find it.

Short version:

I'm not really familiar with SDI in general, and I've only used it once before. That time, once I picked the correct input type it just worked.

This time, not so much. This venue has a Sony Anycast switcher with HD-SDI out. I've looped it's output back to an input and verified that it is working. Catalyst never sees it though. I've tried every combination of settings on both the Anycast and within Catalyst. Everything simply results in video input screen saying SYNC LOSS.

FWIW, I'm using the Phoenix single input PCI-e x1 card.

Any ideas? I've run out of buttons to try, and the client is obviously a little annoyed that it isn't working...
