I am also running fedora 8 x86_64. The cx18 driver compiles and loads except I have not compiled it for the last release of the kernel yet. The firmware was obtained via the link on the cx18 page. I have not been able to get it to work reliably with mythtv. There is a message about a select timeout that happens twice about every 40 seconds. I did try a dd from the /dev/video0 device to a file for a few minutes and then mplayer that file and there were no timeouts. mplayer directly against /dev/video0 would eventually display rubbish and the sound is way out of synch.
