Can't Get ivtv Working

[Dana Merrick]

Hello, forums, it's been a while.

I'm trying to get MythTV running on my Gentoo box. I just bought a fancy Hauppauge PVR-500 card, and I keep having problems with it.

Right now, I just can't get the ivtv module to work, or, more generally, can't get any /dev/video0 or anything similar.

I've looked around the forums and the wiki and the interweb, and haven't found any similar problems (though I've found lots of other problems).

Here is some pertinent information:

Uname shows you running a 2.6.19 kernel:

starfruit ~ # uname -a
Linux starfruit.sinistro.us 2.6.19.1 #1 SMP Wed Jan 24 14:36:38 EST 2007 i686 Intel(R) Pentium(R) 4 CPU 2.40GHz GenuineIntel GNU/Linux

and you've got ivtv-8.2 installed:

Installed versions: 0.8.2-r1(09:49:11 01/25/07)(-fbcon kernel_linux)

The module's in the 2.18 directory too:

insmod: error inserting '/lib/modules/2.6.18-rc7/extra/ivtv.ko': -1 Invalid module format

Ivtv-0.9 is for the 2.6.19 kernels, and 0.8 is for 2.6.18. If you try to emerge ivtv again, it should complain about it. You can downgrade your kernel, or update ivtv.

Oh. My. God.

Thanks for catching that! It was a fact I knew very well, but after recompiling my kernel a million times to get this to work, I guess I just missed it.

Shows how nice a new pair of eyes is.

Thanks so much.

Yeah- it always happens to me. I've got one box with lilo on it, since I was used to it from forever ago, and recently switched to grub for the rest. I always have to reboot the lilo box a couple times and bash my head a bit before I remember that I have to actually run lilo and not just change the kernel symlink to a new kernel...
