Anyone know what would be causing this? I'm using a pvr-150, and MythTV will not recognize the cards.

Some searching (try "PVR150" for example) should reveal how to diagnose these cards and how to upgrade the driver if the card is being misidentified. For example:

http://www.knoppmythwiki.org/index.php? ... ngLogFiles
http://www.knoppmythwiki.org/index.php?page=CompileIvtv

Please search before asking!

I had searched through those before and tried updating the drivers. Those solutions seem to all be for people who had 150's get misidentified as 250's, where my problem is that my card isn't getting recognized at all.

Well, we can't very well help you unless you provide better diagnostic information, and the 2nd item in that list is all about how to collect that information from your log files. Given that you provided almost none with you original post, and that the misidentified PVR-150s are the most common recent problem, I'd also say it was a reasonable first guess based on sparse information and the links were both relevant and helpful.

When trying to configure my PVR-150 MCE (type 1042) in “mythtv-setpup” I too get the error “Could not open /dev/video0 to probe its inputs.”

I tried the “power off” approach, figured I’d start with an easy option, but it didn’t work.

These are the other posts that I have reviewed:
http://mysettopbox.tv/phpBB2/viewtopic.php?t=9101
http://mysettopbox.tv/phpBB2/viewtopic.php?t=9065
http://mysettopbox.tv/phpBB2/viewtopic.php?t=9068

I followed these instructions to compile ivtv 0.4.4
http://www.knoppmythwiki.org/index.php?page=CompileIvtv

I pretty sure that I updated the ivtv drivers correctly, the md5 signatures are good.
Code:
root@mythtv:/# md5sum /usr/lib/hotplug/firmware/v4l*
305dba74bbe5905447add8883f3ecb68  /usr/lib/hotplug/firmware/v4l-cx2341x-dec.fw
5f5fa240ada73c3565f5f7de4c7b5138  /usr/lib/hotplug/firmware/v4l-cx2341x-enc.fw
0661f8b2693fe3123e6234557353eacc  /usr/lib/hotplug/firmware/v4l-cx2341x-init.mpg
3a4803384f749d644ee1f1ca9dcb12fa  /usr/lib/hotplug/firmware/v4l-cx25840.fw


This is what I get for the card when I lspci -v
Code:
0000:02:01.0 Multimedia video controller: Internext Compression Inc iTVC16 (CX23416) MPEG-2 Encoder (rev 01)
        Subsystem: Hauppauge computer works Inc.: Unknown device 8801
        Flags: bus master, medium devsel, latency 64, IRQ 21
        Memory at cc000000 (32-bit, prefetchable) [size=64M]
        Capabilities: [44] Power Management version 2


I think that the root of my problem is related to this error message that is displayed during start up, before the ###ivtv### section.
Code:
“FATAL: Error inserting cx25840 (/lib/modules/2.6.15-chw-2/kernel/drivers/media/video/cx25840/cx25840.ko): Unknown symbol in module, or unknown parameter (see dmesg)”


I get that exact same error when I try to “modprobe cx25840 i2c_enable=1” as suggested in the sample script on this page: http://www.knoppmythwiki.org/index.php?page=HauppaugeOneFiftyInstallation

My /var/log/dmseg has this reference to cx25840 in it (above of the ivtv section)
Code:
cx25840: Unknown parameter `i2c_enable'



Here is the ivtv section from my /var/log/kern.log
Code:

I am new to linux, but have been able to follow lots of awesome posts on this site to get all the other parts of my system working.

Hopefully someone can help me clear this last hurdle.

aloha,
rusty
