NES/SNES 240p have varying hsync period at top of the frame, generating some jitter to output pixel clock signal. That goes beyond capabilities of some receivers, and it sounds like Magewell’s capture card belongs to that group. Check if there is a driver/configuration option to allow higher input bandwidth – that’s how SC512N1-L capture card can be made to accept linedoubled/tripled SNES 240p signal.
