Error when using NTSC
I am having this same error with both 20.2.69 and 20.2.76, but only when I set the input to NTSC sqpxl, which is what the input device is sending. I am using an Osprey 230 capture card, which is listed as a certified device.
If I set the input to PAL 16:9, the stream starts, but our cameras are not PAL cameras, and it messes up the Osprey Config settings, too.
I reverted to 20.2.43, and everything works fine. The latest version breaks something with the Osprey card so that it won't work with NTSC settings.
