I keep trying to use my video capture card that has always worked just fine with OBS up until now. I use it to record things like my Wii U and Xbox 360 that both support AV. OBS Studio just saves the recordings as files that are just black. The video length will be the same but the video itself is just black. I'm using the Windows bersion of OBS on Windows 11 Home (I did have it on the last version of Windows 11 but then I upgraded to the latest and still had the issue)
