The above two lines are all that is needed in your /etc/modprobe.conf

> options msp3400 once=0 simpler=1 simple=0
The ivtv driver can now automatically set a lot of reasonable defaults.
Try removing these two lines and see if it still works. Of course you
may want to leav the options ivtv ivtv_debug=1. You can modinfo ivtv
for the autodetect and default settings.

Remove this line. Modprobe doesn't support the add option anymore.

Add below is no longer supported

This happens with the Redhat (well Fedora) kernel. A plain kernel from
kernel.org doesn't have this issue. Please take a look at this message
from the ivtv list:
Basically, sys_open et al are no longer to be used in kernel modules so
Fedora disabled them to get people to update their drivers (much like
they did with 4K stacks). Not that I have a problem with this, it just
forces people that are on the bleeding edge to make sure they don't keep
old cruft around and gives other distributions time before introducing
things that may break in the mainstream.
