I wonder if anybody has seen anything similar to this behaviour:
- 3Play 4800 - recently updated [made no difference]
- OBVan receiving 6 HD-SDI feeds
- Sometimes in mid-game input 1 & 2 suddenly only show black video, keeps on recording but video is black
- If same feeds are also routed to input 7 & 8 they will work normally

My main problem currently is that I have not found a way to re-create this outside live broadcast.

So far I have updated the software - seemed to work for a couple of games and then showed this behaviour again.

I'd appreciate any pointers as to what might be in play here before I register this as a formal support case with NT Support.
