problem setting ivtv tuner channel in 0.19 w/ ivtv 0.4.x?

I upgraded to 0.19 rpms (current atrpms, so I think it has -fixes in
it), and it installed the new ivtv 0.4.1 with it. I have an external
tuner (Dish) and was getting nothing put static for live tv and
recordings. I followed all the instructions I could find to fix it.
I've done the following:

* Removed ivtv and completely reinstalled, now at 0.4.4. (This solved
the init.mpg firmware issue as part of yum's file dependancy issue)

* Updated lirc, alsa, etc. (To fix my remote, have a PVR-350)

* Removed all card setups (did this 5x times) in mythtv-setup per:
mythtv.org/wiki/index.php/Frequently_Asked_Questions#Q:_I_upgraded_my_ivtv_drivers_to_the_latest_version_and_now_I_can.27t_record_anything.

* Run mythfilldatabase to update everything...

After doing all of the above, I was still receiveing static. I
manually ran this command and it started tuning the input properly:

ivtv-tune -c3 -d/dev/video0

So to "fix" it, I've got that command running when my system boots up,
but shouldn't myth still be handling setting the tuner to channel 3?
Did this break in 0.19? I have channel 3 set in mythtv-setup where it
should be.

One thing that's weird, is the mythtv wiki (link above) says my tuner
will be "Tuner" and not "Tuner 0", but it's still listed as "Tuner 0".
Something wrong with my upgrade to ivtv or something?

Thanks for you help, sorry to post to the dev list but this seems like
a bug... :(

I'm assuming you mean the setting:

Preset tuner to channel
Leave this blank unless you have an external tuner that is connected to
the tuner input of your card. If so, you will need to specify the preset
channel for the signal (normally 3 or 4).

(otherwise, channel 3 isn't set where it should be ;). If so, there was
a discussion on the -users list where a couple of people reported it was
not working for them in 0.19.

Unfortunately, though, I haven't had a chance to look at it, yet. Out
of curiosity, though, what do you get when you run:

mysql -umythtv -p mythconverg -e 'select * from cardinput\G'

(If it's too big, feel free to e-mail me directly--with the same subject
on the message.)

Thanks,
Mike

I think so. Look around for an old version of ivtvctl. That might
be interfering.

I ran updatedb and then:

[root [at] localhos mythtv]# locate ivtvctl
/usr/bin/ivtvctl
[root [at] localhos mythtv]# ivtvctl --version
ivtvctl version 0.4.4 (development snapshot compiled on Wed Mar 15
05:56:34 2006)

as far as I know, no old ivtvctl's lying around. :(

Yup, it's set to 3. Made sure to put that in there each time I redid
the tuner card, channels, sources, etc. I deleted all of them many
times (since that's what the FAQ says to do).

That thread describes the exact problem I have with my PVR-350 too. I
came up with the same work around of using a startup script and
running ivtv-tune to workaround the issue...

Could be a bug in IVTV (or Mythtv) that's specific to PVR-350's. Seams
the common thing between my setup and the thread you mentioned.

Also, in poking around, looking at dmesg I found this at the very end
(don't think this is relevant, just mentioning incase it's helpful):

I don't know what cx8800 or bttv is, lirc stuff for different
chipsets? I just have a PVR-350, no other cards... Don't know where
that stuff came from, part of the lirc rpm I guess. Could this be
causing mythtv not to be able to set my tuner channel to 3?

Let me know if there's anything I can test, would be glad to help any
way I can...

-Kenneth
