Post subject:  IVTV-0.4.3 with a PVR-150 and HD-3000
Hi all,
I installed ivtv-0.4.3 the other day on my R5A30.1 system, which was running ivtv-0.4.0 at the time. I followed tjc's nice write up on the wiki. Everything was working fine with both my PVR-150 and my HD-3000 until I did a cold boot. Now, I cannot get and signal on the PVR-150. When I select it as a source, the screen goes black for about 15 seconds and I'm then kicked back to my DVB Input (the HD-3000). Nothing is trying to record on the PVR-150. When I check my mythbackend.log, I see this error everytime I tried to access the PVR-150:
Code:
Error getting codec params
IVTV_IOC_G_CODEC:: Bad address

I checked the IVTV Mailing list and only came up with 3 threads from 2004 that did not provide me a solution.

I cleared my card settings several times, attempting several different combinations of devices for my PVR-150. i.e. /dev/video0 S-Video or /dev/video1 S-Video0 etc. I also tried to set up the PVR-150 first (so it's input is selected first when I select "Watch TV" but that did not solve the issue.

Here is the ivtv output of my dmesg:

I found a file at /etc/sysconfig/ivtv that says it configures ivtv at boot time. It claims that it sets everything to the defaults (i.e. /dev/video0). Can the cfg-0 that it reads from be changed from /dev/video0 to /dev/video1?

Any insights are definately appreciated. Let me know if you need more info.

cfg-0:
Code:
# /etc/sysconfig/ivtv/Readme
#
#   A KnoppMyth configuration file.
#
# This file is an example configuration file for tv tuner cards
#  that use the ivtv driver module, such as the PVR-250.
#
# If a copy of this file is placed in the /etc/sysconfig/ivtv
#  directory with the name of (for example) cfg-0, then, when
#  /etc/init.d/set_ivtv_params gets run during boot, the ivtv
#  card that represents /dev/video0 will have the following
#  parameters set.
#

# IVTV_TUNER is the tuner input selection value,
#  if not set the Default of '0' will be used.
#IVTV_TUNER='0'

# IVTV_TYPE is the type of the tuner.  Possible values
#  are NTSC or PAL.  A default value of 'NTSC' will be used if
#  this is not set.
#IVTV_TYPE='NTSC'

# End

I suspect didn't reboot the first time and still have "Tuner0" in your configration rather than the modern "Tuner" for the PVR-150 and 500 cards. Please revisit the last two steps in the directions on the wiki.
Quote:
    * Reboot the system.

    * After it comes back up you will need to stop the backend, run mythtv-setup, clear your capture card settings, restablish them and the input connections, and finally exit mythtv-setup and restart the backend. Note that with the new driver you will see a different set of inputs for PVR-150 and PVR-500 cards.

I must have done that a hundred times. :wink: Just to be sure, I went ahead and did it again, but there is no joy. However, I have made a bit of progress, although not without issues...

The ivtv-0.4.3 documentation on the http://ivtvdriver.org website says:
Quote:
If you are installing a dvb card together with a PVR card, try using the kernel tveeprom instead of the ivtv tveeprom-ivtv module. Numerous users have reported this combination enables the use of PVR cards and dvb cards together. Known combinations include Hauppauge PVR350 and 500 with the pcHD3000....

...We just want to make the kernel look for the dvb version module, instead of the ivtv version module when it looks for 'tveeprom.ko'.


Based on that I did a little tinkering.
Code:
# cd /lib/modules/2.6.13.2-chw-3/ivtv
# mv tveeprom.ko tveeprom.ko.HIDE
# cd /lib/modules/2.6.13.2-chw-3/kernel/drivers/media/video
# cp tveeprom.ko /lib/modules/2.6.13.2-chw-3/ivtv/tveeprom.ko
# /etc/init.d/mythtv-backend stop
# mythtv-setup (say yes to clear cards, no to clearing channels)


I set up my HD-3000 as a DVB card with it's proper video source. I then selected the MPEG-2 card (PVR-250, 350) and used /dev/video1 and the S-Video 0. (My other option was /dev/video0 and S-Video, but that did not work.) I exited the setup and
Code:
# shutdown


Unplug and wait 30-60 seconds. Plug back in and fire it up. On boot everything looks ok, except the tuner card comes up as <unknown>. Into mythtv I go and I select "Watch TV." My DVB input is looking and sounding good. I change tuner cards to the PVR-150 and I get picture, but my sound is distorted. It sounds like the audio is being played back at the wrong sample rate. High pitched, tinny is the best I can describe it. I know there are oodles of posts on this forum about similar audio issues. This is becoming a little more trouble than it's worth for me. I think I'm going to revert back to my ivtv-0.4.0 which was working fine for me. I need to stop upgrading just for the sake of upgrading... I need to leave well enough alone! :)

I had the firmware right...

I'm wondering if there is a bug when a PVR-150 and HD-3000 are installed together with the 0.4.3 driver. The ivtvdriver.org docs mention a 250/350 are known to work, but there's no mention of a PVR-150 working with a HD-3000 installed...

Most of the compatibility issues with PVR-x50/PVR-500 and HD-3000 cards come down to module load order, and there's no difference between the [23]50 and 150/500 on that count. I've currently got the HD-3000 yanked out of my box because given my crappy reception, hassling with the module order everytime I do an upgrade is a nusciance. The 0.4.3 dependency on the hotplug firmware loader just makes this more difficult.

right.. some how I got it in my head that you were using a pvr350.

I am apparently struggling with the same issue. Has anyone gotten the ivtv drivers to play nice with the HD3000 (dvb) drivers?
Author:  tkoster [ Fri Mar 17, 2006 7:19 am ]
Post subject: 
Resolved: the latest ivtv drivers appear to let the dvb drivers take the highroad. In the process they moved my 350 from video0 to video1. It took some playing in mythtv-setup, but now is working.

For the benefit of others... There was a patch posted in this thread that has fixed my tinny audio issue with a PVR-150. Don't know how to patch? Try this:
Code:
