Here's what I get when I do:

I don't have a modprobe.conf but do have a modules.conf. It doesn't
have any line describing the tuner number in it.

Since I'm using KnoppMyth, I'm guessing I need to look in the
/etc/mythtv/modules/ivtv file but have the tuner line commented out:
alias char-major-81 videodev
alias char-major-61 lirc_i2c
#options ivtv debug=1
#options tuner type=2
options msp3400 once=1 simple=1
install ivtv /sbin/modprobe tuner; /sbin/modprobe msp3400;
/sbin/modprobe saa7115; /sbin/modprobe --ignore-install ivtv;
/sbin/modprobe ivtv-fb; /sbin/modprobe lirc_i2c
remove ivtv /sbin/modprobe -r --ignore-remove ivtv && /sbin/modprobe -r
saa7115 && /sbin/modprobe -r msp3400 && /sbin/modprobe -r tuner &&
/sbin/modprobe -r ivtv-fb && /sbin/modprobe -r lirc_i2c
I'm guessing that ivtv is auto-detecting the tuner type. Is there a
different way to do this? or to correct this problem?
Thanks.
