I have been struggling with Linux drivers for the above mentioned card. 
Doing an lspci -v reports:

03:00.0 Multimedia video controller: Conexant Systems, Inc. CX23885 PCI
Video and Audio Decoder (rev 02)
        Subsystem: Hauppauge computer works Inc. Device 71d3
        Flags: bus master, fast devsel, latency 0, IRQ 16
        Memory at ef800000 (64-bit, non-prefetchable) [size=2M]
        Capabilities: [40] Express Endpoint, MSI 00
        Capabilities: [80] Power Management version 2
        Capabilities: [90] Vital Product Data
        Capabilities: [a0] MSI: Enable- Count=1/1 Maskable- 64bit+
        Capabilities: [100] Advanced Error Reporting
        Capabilities: [200] Virtual Channel <?>
        Kernel driver in use: cx23885
        Kernel modules: cx23885

I have been googling a lot and I am somewhat confused if the current drivers
supports video capture on the S-Video connector.  Most mailing list entries
say that only digital capture is possible, however I did notice some
changes in the cx23885-cards.c:

        [CX23885_BOARD_HAUPPAUGE_HVR1200] = {
                .name           = "Hauppauge WinTV-HVR1200",
                .portc          = CX23885_MPEG_DVB,
                .input          = {{
                        .type   = CX23885_VMUX_TELEVISION,
                        .vmux   = 0,
                        .gpio0  = 0xff00,
                }, {
                        .type   = CX23885_VMUX_DEBUG,
                        .vmux   = 0,
                        .gpio0  = 0xff01,
                }, {
                        .type   = CX23885_VMUX_COMPOSITE1,
                        .vmux   = 1,
                        .gpio0  = 0xff02,
                }, {
                        .type   = CX23885_VMUX_SVIDEO,
                        .vmux   = 2,
                        .gpio0  = 0xff02,
                } },
        },

Which sort of indicates that the driver is aware of the connector.  Can
anybody help me what is the current status of this driver/card combination?
