Need more info really....
Most likely reason is the the kernel/ivtv tveeprom problem.
Next most likely is that Fedora is loading the wrong cx88 module: the
NTSC one, and not the ATSC one.
You don't say which kernel version you have. If its a 'from-the-iso' FC4
install you have something like kernel 2.6.11-1369.
You should update/upgrade. The kernel modules are lots better in 2.6.15.
If it's actually bare metal you might as well go directly to FC5!
Make sure that you do not have an ivtv version of tveeprom.ko hanging
around in the lib/modules tree. Run depmod after renaming/removing.
Check dmesg to see if the cx88-dvb module is being loaded. If so you
will see reference to the firmware for the oren5132 (or somesuch) being
loaded. If there is no reference to that, but instead references to
cx8800 then you need to clear the modprobe.conf file of any cx88 module
load commands, and put some lines into rc.local to modprobe -r cx8800
and modprobe cx88-dvb.
Somewhere in one of the /lib/modules/modules.xxx files, I saw a listing
of modules and what appear to be hardware addresses. The cx8800 is
referenced at something like xxxxxx00 while the cx88-dvb is referenced
at xxxxxx02. I suspect that that ordering is why the kernel loads the
'wrong' module first.
