I have an intel em64t-based myth backend system with one hauppauge pvr350 NTSC tuner card and one pchdtv3000 ATSC tuner card. Both work perfectly if they are the only one whose modules are installed. But as soon as I install the second module, the pvr350 tuner quits working.

If anyone has any ideas, I'd love to hear them. following is the relivant part of my dmesg.

Code:

What I had to do, before I just got tired of fighting with it and left the HD3000 out for the time being, was force the ivtv driver to load first. Otherwise the PVR card wasn't recognized properly. Here's how to check if you have the same problem.

1) Run the following command: lspci | grep Multimedia

2) If you see something like this:
Code:
0000:02:08.0 Multimedia video controller: Conexant Winfast TV2000 XP (rev 05)
0000:02:08.2 Multimedia controller: Conexant: Unknown device 8802 (rev 05)

(which is really the HD3000) Showing up before any PVR devices, which look like this:
Code:
0000:02:0a.0 Multimedia video controller: Internext Compression Inc iTVC16 (CX23416) MPEG-2 Encoder (rev 01)

Then you have the same problem.

i don't seem to be having your problem... here's the output of my lspci:
Code:
lspci | grep Multimedia
0000:01:01.0 Multimedia video controller: Conexant CX23880/1/2/3 PCI Video and Audio Decoder (rev 05)
0000:01:01.2 Multimedia controller: Conexant CX23880/1/2/3 PCI Video and Audio Decoder [MPEG Port] (rev 05)
0000:01:02.0 Multimedia video controller: Internext Compression Inc iTVC15 MPEG-2 Encoder (rev 01)

I can't be sure it's correct, but it seems ok to me...

As I said first... both catds seem to work for the most part. Even with both modules insmodded, they basically work... meaning there are appropriate devices in /dev, and if i have mplayer grab them, output looks great. But when I try to tune the pvr350 with ptune-ui.pl, nothing happens.

Thanks for the reply... but does anyone have any other ideas??

You may still have an ordering issue since the HD3000 is seen before the PVR card. Check the ordering of modules in your /etc/modules file to make sure that the ivtv driver gets loaded earlier than the other.

I was having the same problems...

and then I installed the PVR-350 first then the pcHDTV3000 (as well as modified the /etc/modules file so ivtv is higher on the list than the hdtv3000 drivers)

my lspci looks like this:

Code:
0000:02:04.0 Multimedia video controller: Internext Compression Inc iTVC15 MPEG-2 Encoder (rev 01)
0000:02:06.0 Multimedia video controller: Conexant Winfast TV2000 XP (rev 05)
0000:02:06.2 Multimedia controller: Conexant: Unknown device 8802 (rev 05)
