9.) nano /etc/modprobe.d/ivtv

--Note: You probably don't have this file unless you're upgrading. Just create it from scratch.

insert the following for PVR-150 NTSC non-mce

alias char-major-81 videodev
alias char-major-81-0 ivtv
alias char-major-61 lirc_i2c
options ivtv tuner=39,50 ivtv_std=1,1 tda9887=0 mixer_input=2
add above ivtv lirc_dev lirc_i2c

insert the following for pvr-150 MCE (type 1042)

alias char-major-81 videodev

alias char-major-81-0 ivtv

alias char-major-61 lirc_i2c

options ivtv tuner=47

options saa7127 i2c_enable=-1

options cx25840 i2c_enable=1 no_black_magic=1

-- The add above line gave me an error on startup, so i commented it out. I also needed to add "options wm8775 mixer=2" to /etc/modprobe.d/wm8775 so i could get just composite sound with no static. - Nick Bonfatti

--Fix: edit /etc/mythtv/modules/ivtv and comment out the "options tuner=2" line
This one took me 2 hours to find. Now this works like a dream!!! -KF

--Fix: remove the eeprom module and modprobe the tveeprom module. With this loaded, your tuner will be detected automatically so you do not have to guess its type. I use the following script, which goes slower than necessary but the extra steps are helpful in debugging if anything goes wrong. For extra debugging, most of these modules support a debug=1 parameter which logs everything to dmesg instead of just detection and errors.

echo Loading IVTV drivers.
echo Unloading eeprom
rmmod eeprom
sleep 1
echo Loading tveeprom
modprobe tveeprom
sleep 1
echo Loading videodev
modprobe videodev
sleep 1
echo Loading cx25840
modprobe cx25840 i2c_enable=1
echo Loading tuner
modprobe tuner
sleep 1
echo Loading wm8775
modprobe wm8775
sleep 1
echo Loading ivtv
modprobe ivtv

Note: IVTV creates a new tuner module. I've had to rename the tuner module that came with the kernel to make the video stable and static free: mv /lib/modules/2.6.9-chw-4/kernel/drivers/media/video/tuner.ko /lib/modules/2.6.9-chw-4/kernel/drivers/media/video/tuner.ko.old
