[mythtv-users] pvr-150 tuner type 47 problem

I see you're using -p 6 and - p 7 for your two PVR-150 cards. Did you
try other values for the -p option for ivtv? Mine used -p 4 for the
tuner input and -p 0 for S-Video.

I would first verify that the signal you're feeding it is good and is on
a known channel (connect it directly to a TV), then try this:

ptune.pl --channel 4 --input /dev/video0 (change channel and device as
appropriate)
ivtvctl -d /dev/video0 -p 0
ivtvctl -I

and look to see if it has a good signal - the first two lines should 
tell you. If not, repeat the second two commands with -p 1 through -p 8 
and see what they give you.
