Q&A
Why can't the MPB741G capture the camera feed?
Please first confirm whether the camera's resolution is set to 1080i.

Why is the signal seen through OBS or other capture software on the computer stuck or frozen?
This indicates that the signal source contains HDCP-protected content, which the MPB741G does not support capturing.
