    Help installing Conexant CX23880 TV input card

    Hello, first time posting on the forums. Most of my initial issues have been solved by googling or lurking, but I've recently hit up against a brick wall when it comes to installing a "Conexant CX23880" PCI tv tuner card.

    I have the card physically installed, and a terminal prompt of "lspci" will give the following listing:
    Code:
    01:05.0 Multimedia video controller: Conexant CX23880/1/2/3 PCI Video and Audio Decoder (rev 05)
    Various help sites have promised to solve all my woes, such as this linuxtv.org page and others, but despite my following them to the letter, nothing appears to work. Compiling and installation seems to work, but after I reboot, this is all that I am getting:
    Code:
    griffith@griffith-dvr:~$ sudo modprobe -r cx8800
    griffith@griffith-dvr:~$ sudo modprobe -r cx88xx
    griffith@griffith-dvr:~$ sudo modprobe cx8800

    I don't know what this all means. Did I not compile video4linux correctly, or something? Anything to get /dev/video0 to appear would be appreciated. (I think that's what I need... right?)

    Not much help. but I have just tried the same scenario as you have described, and I have identical symptoms.
    Are you running 64bit kernel?

    UPDATE: I have gone back to a Fiesty installation, and got past the problems above. I now have some contact with the card (Dvico FusionHDTV DVB-T Pro). I still don't have any TV but the problem has moved on considerably.
