On Fedora, 'modprobe -r cx18' removes the module. I guess Mandriva uses
something slightly different?

I did a 'modprobe -r cx18' just now.<BR>

You have an old version of v4l2-common.ko lying around. Obviously
something went wrong with the build & install of the latest v4l-dvb
repository.

<BR>
When you say 'old' what do you mean? and old build, or old as in an old version from a different download?<BR>
<BR>
<BR>
Do you think this could have come from some other install and not the one I just did? Because I just downloaded the driver and just installed it. So I should not have an old version unless somehow its part of a mandriva package I installed for some reason.<BR>
<BR>
Looks like I have MythTV Installed, but no ivtv driver. Should I uninstall mythTV till I get this part working?<BR>

The symbol should be defined in videodev.ko and not exists in v4l2-common.ko

All these missing symbols exist in the videodev.ko module (I think), so
that module didn't load due to the symbol collision with the
(apparently) old v4l2-common.ko module.

OK, what I did was <BR>
lsmod | grep v4l<BR>
<BR>
and I did see the v4l mod still loaded. I think it was not unloading because I was not building it and make unload wasnt working. I dont know. ANyway, I just did a full build, then a make install, then a make unload, then another<BR>
<BR>
lsmod | grep v4l<BR>
<BR>
and it showed nothing. So I figured I got it unloaded. But then when I do modprobe <BR>
