Add the tuner Hauppauge WinTV-HVR-4000 to the Video capture driver.

[User_Z]

The HardwareInfo website has a list of tuners that are supposedly supported by the system. I bought one from this list: Hauppauge WinTV-HVR-4000. Installed this tuner in the computer, but the TV program does not work. The system in Device recognizes it as Conexant Systems Inc. CX23880 ... devices:

Conexant Systems Inc. CX23880/1/2/3 PCI Video and Audio Decoder
Conexant Systems Inc. CX23880/1/2/3 PCI Video and Audio Decoder [Audio Port]
Conexant Systems Inc. CX23880/1/2/3 PCI Video and Audio Decoder [MPEG Port]

device/id      0x8800, 0x8811, 0x8802
device/subtype 0x80
device/type    0x4
device/vendor  0x14f1

In the driver.c file that the site sends to, only one supported device is written, and then another model:

static card_info sCardTable[] =
{
    { 0x14f1, 0x8802, 0x0070, 0x9002, "Hauppauge WinTV-NOVA-T model 928" },
    { /* end */ }
};

How to make my tuner work?

Maybe you just need to add my model there?

Write something like this:

static card_info sCardTable[] =
{
    { 0x14f1, 0x8802, 0x0070, 0x9002, "Hauppauge WinTV-NOVA-T model 928" },
    { 0x14f1, 0x4, 0x80, , "Hauppauge WinTV-HVR-4000" },
    { /* end */ }
};
