You've got the wrong tuner specified. If you have a line "options
ivtv tuner=2" (or whatever number), take it out of your
mod{probe,ules}.conf.
In mythtv-setup, I've tried changing the Cable system from 'Default'
to 'US' to 'US-HRC' and 'Broadcast' with no change (actually my box
locked up when it was set to 'Broadcast' - still same snow seen.
Not a frequency table problem.
I've tried fine-tuning a couple channels (though I really don't know
what I'm doing) and did get different looking snow (squggly lines,
black bands, etc) but nothing anywhere near resembling a picture.
Not a fine-tuning problem.
Info:
[EMAIL PROTECTED]:~$ dmesg | grep ivtv
This is useless because some of the most important information (all
important information in this case) is from modules used by ivtv (i.e.
the tveeprom and tuner modules).
This is how you should report ivtv initialization information if you
don't feel like copying/pasting from a text editor:
tac /var/log/messages |
sed -n '/=\ \ END INIT IVTV\ \ =/,/= START INIT IVTV =/p;
/= START INIT IVTV =/q' |
tac
(assuming your log is /var/log/messages) or
dmesg | tac |
sed -n '/=\ \ END INIT IVTV\ \ =/,/= START INIT IVTV =/p;
/= START INIT IVTV =/q' |
tac

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.
