I am working to install on a:
P3 550 (Katmai)
PVR 350
ATI Rage 128

Everything goes well, until I get to the tuner section of the setup. When I try to add a tuner, the installation fails with a message can't open /dev/video and a segmentation fault. I have tried both i586 and default 586 packages.

The mythtv-backend.log lists two error messages:
error creating /.qt
can't open /dev/video

I have not tried using the XF86Config-4.pvr35... file yet as I just want to get it working on the monitor before sending output to TV.

My XF86Config-4 file seems to have detected the ATI card, and /dev/video exists. I am a relative Linux/Debian newbie and not sure how to fix this video device issue. It does not seem to be just a myth tv issue. LILO was not installed properly, so when I updated lilo.conf and ran /sbin/lilo, I got a message about no video card being available, although X starts up fine.

As a perhaps related note: I had to add the network interface entry (only lo was configured on installation) and the ALSA mixer cannot be found. So, this seems to be more of a device configuration issue in Knoppix/Debian than a MythTV issue.

Any help would be greatly appreciated.

You can ignore the .qt error. When the system boots do you see where it states which tuner is found? While the i586 debs should work w/ a P3, the P3 is an i686 class processor(as root install-i686-l). The sample file for the 350 is just that, a sample in order to get TV out work, follow the instructions on the IvyTV wiki or the post here on the forum.

I updated to the i686 debs, and re-ran the configuration. When I try to configure the tuner, I get the following messages in xterm:
Couldn't open /dev/video to probe its inputs
Segmentation Fault

When I look in /var/log/messages, I see mtyhtv-kernel messages which refer to vga16fb and fb0, but nothing that refers to tuner

In mythtv-backend.log, I see the following:
/dev/video: no such device
Couldn't find input: Television on card
Cable is defined, but isn't attached to cardinput

Noticed one more thing --above the could not open /dev/video for input message, there are two messages:
mythtv: could not connect to socket
mythtv: Connection refused

It is configured to use 127.0.0.1 and the loopback adapter seems to be working.

You didn't answer my question.

I don't see what tuner is found. I looked in /var/log/messages and did not find a reference to tuner, and I looked in mythtv-backend.log and reported the messages relating to the tuner. Was there another question or is there some other place I can find out which tuner is found?

if /var/log/messages has no references to tuner then something is definitely wrong. do lsmod | grep ivtv if nothing shows up ivtv is not loading and that is the device driver for the pvr350, which also takes care of making /dev/video work (for a short explanation).

OK, thank you for being patient with me. lsmod | grep ivtv returns nothing, so I assume I need to get ivtv from source forge, install and follow the instructions of the other posts for configuring ivtv with the pvr350.

IvyTV is installed, if your card isn't being detected then that is your problem. Do you should see something like this:
or If you don't see either, something is wrong with your card, make sure it is well seated or try another PCI slot.

Yes, when I do lspci | grep con I do get the entry for the Multimedia video controller, so the card is being found.

Reboot the system, if you're using bootsplash, press <F2> for verbose mode. Do you see where it states "Checkinf for Multimedia video controller"? It should state "KnoppMyth found" and what it found. Does it?

Yes, I see this message as it is booting, although it is not logged to /var/log/messages. It says:
KnoppMyth found Internext Compression Inc iTVC15 MPEG-2 Encoder (rev 01)

Odd... As root:
Do you see:If not If the firmware is there, try another PCI slot.

BTW - Any particular reason why we're still using this older version of the PVR-x50 firmware?

Other than the fact it works , that is the version I'm authorized to distribute with KnoppMyth. Is there a reason to use a newer version(other than the fact it is newer)?
