Indeed.

$ lspci | grep Conexant
04:00.0 Multimedia video controller: Conexant Systems, Inc. 
CX23880/1/2/3 PCI Video and Audio Decoder (rev 05)
04:00.1 Multimedia controller: Conexant Systems, Inc. CX23880/1/2/3 PCI 
Video and Audio Decoder [Audio Port] (rev 05)
04:00.2 Multimedia controller: Conexant Systems, Inc. CX23880/1/2/3 PCI 
Video and Audio Decoder [MPEG Port] (rev 05)
04:00.4 Multimedia controller: Conexant Systems, Inc. CX23880/1/2/3 PCI 
Video and Audio Decoder [IR Port] (rev 05)

Maybe it's time to change the subject from "How to capture composite
