It depends on the chip set that you have on your card.
If it is a Conexant 878, it should be auto detected by the 2.6 series kernel.
If it is a Philips chip, then you have to go with a 2.6.15 kernel and cross your fingers kinda thing (I haven't yet had the chance to test the newer kworld cards with the Phillips chips).

The card seems to be recognized, but as I've said, the problem is that I'm not seeing anything. Would that have anything to do with the detection?

-Edit-
I took out my graphics card and confirmed that it has a connexant chip.

Also, here is dmesg | grep bttv

That shows that you set the value your self and it is not going to use any autodetection as you are forcing the settings. So unless this has changed...
I'm not sure what card type you should be using though. The one you selected might be correct. Does this board have a tuner on it? This driver sure thinks it does.

Ok, I the dmesg I showed before was after changing my modprobe.conf as suggested by jameswilson. After removing that, I get the following dmesg:

With these settings, zoneminder is completely unresponsive to whether or not there is a video signal, and shows a red screen regardless of whether or not there is a signal.

Also, thanks for all the help. The response time here is amazing.

Okay, I think we need to back up a bit.
First what linix flavor are you using?
Kernel version?
Is there any chance you could post a picture of the card?

Regards,
Corey

I'm using Ubuntu, Breezey Badger. The kernel version is 2.6.12-10-386.

I don't reall have the resources to take a picture of the card myself, but this picture is the generic picture that resellers put with the card:

Ok, I finally got to try the video card in a system with more resources. I used the Live CD because I'm not allowed to install an operating system on this machine, and it's normally windows. I used Xawtv to look at the video card, and saw nothing but black images.

The thing that confused me, was that the signals were labeled things like "television" and "composite 1". Are these arbitrary names, or is it expecting a kind of signal it's not receiving?

[zoneminder]

They are labels that usually correspond to the inputs that your card would expect but other than that are not usually significant.

i had the same issue with a similar card with debian... I was running an older 2.6 series kernel and then updated to the 2.6.15 kernel and it solved my 'black screen' issues in fact my dmesg output was almost identical to yours.
