I did a 'modprobe -r cx18' just now.

When you say 'old' what do you mean? and old build, or old as in an old
version from a different download?
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.
Looks like I have MythTV Installed, but no ivtv driver. Should I
uninstall mythTV till I get this part working?

Looks similar. I am not sure what you are showing me with this dump
though? What does it mean? Should it match something?

OK, what I did was
lsmod | grep v4l
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
lsmod | grep v4l
and it showed nothing. So I figured I got it unloaded. But then when I
do modprobe
[EMAIL PROTECTED] carl]# modprobe cx18

If you look at the date of these files, some are from June, and some are
from today's build. What does this mean?
Thanks for the help.
