What version of the cx18 driver does your distro have?

$ /sbin/modinfo cx18
filename:       /lib/modules/2.6.27.9-159.fc10.x86_64/kernel/drivers/media/video/cx18/cx18.ko
version:        1.1.0
license:        GPL
description:    CX23418 driver


Versions earlier than 1.0.4 won't work reliably.  If you have an early
version, follow the steps here to get the latest:

http://www.ivtvdriver.org/index.php/Cx18#Obtaining_the_driver


If you do have a v1.0.4 or later version of the driver, please ensure
you have the firmware files:
 
http://dl.ivtvdriver.org/ivtv/firmware/cx18-firmware.tar.gz

untarred and stored in the directory in which your distribution expects
them.


If all that is OK.  Try

$ sudo /sbin/modprobe -r cx18
$ sudo /sbin/modporbe cx18 debug=15

And send the logs from module load to after the start of the first
capture.
