Good afternoom, If I'm right, You are talking about the H3 microcontroller datasheet, at the section that talks about video output it refers to a MUX that controls wich output is enabled, I think CVBS is the option 1 (the one that is not enabled by default), so you need to change the configuration file from 0 to 1 in order to activate the CVBS output.
