I am not sure whether I need the saa7127 module, I think it's only on
the PVR-350. I can get sound when I do a cat /dev/video0 >
somempeg.mpeg, but with mythtv there's no sound...

My modprobe.conf:
# ivtv stuff
alias char-major-81 videodev
alias char-major-81-0 ivtv
options tuner type=29
options ivtv ivtv_debug=1 tuner=29
options msp3400 once=1 simple=1
#add below ivtv msp3400 saa7115 tuner

And a little script to start ivtv:
modprobe i2c-core
modprobe i2c-algo-bit
modprobe tuner type=29
modprobe msp3400
modprobe videodev
modprobe saa7115
modprobe ivtv
test_ioctl -u 0xff
test_ioctl -p 4
test_ioctl -f width=720,height=576
test_ioctl -v input=3,output=1
