NVIDIA Broadcast (camera) and separate camera input freezes camera input?

Hi,

I have an HDMI Camera source (Canon R6), an AVER Media Live Duo capture card, and a third external USB capture device that supports UVC, as NVIDIA Broadcast don't work with HDMI as of now. My HDMI camera feed is currently wireless, and the receiver has 2 outputs, so the 2 video feeds into the computer are essentially identical, albeit running into the computer in 2 completely different ways. The wireless is not the issue - the feed is a stable 1080p 60fps.

What I'm trying to do is layer over the NVIDIA Broadcast (background removed) feed directly on top of the normal camera feed, and that way I can "stand in front of" a floating computer window, that is suspended in my studio. (Think The Sushi Dragon's floating windows - shown below). the Main camera feed is the background, and then I can put a window hovering in the middle of it, then I can walk in front of the screen and point to things, without needing a green screen.

The problem is that whenever I try to add both sources, my the image coming from my main capture card freezes/goes jittery. The NVIDIA Broadcast feed is fine. I'm not sure why this happens. The obvious reason would be if I was using the same camera source to feed both NVDIA Broadcast and OBS simultaneously, and the computer gets mixed up trying to understand which program is using the video source. However, in this instance they are completely different video sources (despite the fact they are actually coming from the same camera).

I realise The Sushi Dragon runs several computers simultaneously do do some of the things he does, but in this instance I don't see why OBS can't handle 2 completely separate video sources, assuming one of them is NVIDIA Broadcast?

I have an RTX 3060, Ryzen 5600, 32MB ram.

Any thoughts?
