Ok,  I seeming have done all the neccessary things to get it up and
running.  However, when I go to watch tv all i get is noise.  I know the
cable is good (tested on the tv)  so what do I do next?  thank you for
your help

here is my set_ivtv_params:

root at mythtv:~# more /etc/init.d/set_ivtv_params
/usr/local/bin/ivtvctl -d /dev/video0 -u 0x3000 -f width=720,height=480
-p 6
/usr/local/bin/ivtvctl -d /dev/video0 -c
dnr_mode=0,dnr_temporal=4,dnr_spatial=4
/usr/local/bin/ivtvctl -d /dev/video0 -x 0

/usr/local/bin/ivtvctl -d /dev/video1 -u 0x3000 -f width=720,height=480
-p 6
/usr/local/bin/ivtvctl -d /dev/video1 -c
dnr_mode=0,dnr_temporal=4,dnr_spatial=4
/usr/local/bin/ivtvctl -d /dev/video1 -x 0


here is my module/ivtv:

root at mythtv:~# more /etc/mythtv/modules/ivtv
alias char-major-81 videodev
alias char-major-61 lirc_i2c
#options ivtv debug=1
#options tuner type=2
