Hello all
I need some help getting this card to work on my two year old mythbox that's been tunerless since day one.
I installed the card, ivtv-utils and did pacman -Syu
but, I have no video devices in /dev
This is whats happening during startup.

I just got this tuner card used off eBay so I don't know if something is wrong with the card itself or not. It seems to be in pretty good shape, it came with all the original packaging. If all else fails I can drag out an old system and install Windows Xp on it to test it.
Any help with this problem would be appreciated. Thanks.

I tested the card. It works. I used the program AMCAP that was on the driver disc and a VCR as input.
One tuner (I'm guessing the second) had a bit of static.. I'm not sure why (not enough juice?) but, if it does it in MythTV it kinda defeats the purpose getting the 500 over the 150.
Here is some output from prodinfo.exe if it will help:

Again any help with this problem would be appreciated. Thanks.

Your problem looked interesting, so I thought I'd dig down underneath the covers. But this is a single person's opinion as a driver developer, but not a Linux driver developer... A massive difference... So take it with a healthy dose of skepticism.
But the bottom line is my opinion is that you might want to head on over to the LinuxTV.org folks and see what they have to say.
The tldr; version follows:
I drilled down on this error message: "ivtv0: Cannot request encoder memory region."
That comes from the drivers/media/pci/ivtv/ivtv-driver.c file... and here's the snippet of code from the latest "linux-stable" code tree in the "ivtv_setup_pci" function:
if (!request_mem_region(itv->base_addr, IVTV_ENCODER_SIZE, "ivtv encoder
")) {
IVTV_ERR("Cannot request encoder memory region.\n");
return -EIO;
}It appears that call is attempting to map the PCI IO memory for your PCI adapter... and it fails with that -EIO (-5) error code.
There can be multiple reasons for the failure, but the LinuxTV folks may be able to determine the reason for your particular instance.

Thanks for the advice. I was thinking about going to the ivtv-users mailinglist but, I was playing around with the card again today and I got it to initialize in the mythbox... not sure what did it. I moved a sata cable to a different connection to make more room and had to make changes in the bios so it would boot again.
I also re-seated the card couple times before booting up.
But, unfortunately I can't get mythtv-setup to find any channels during a scan, but I'm pretty sure that's a mythtv problem.
Plus, the picture on the second tuner is still staticky. So.. I pretty much have only one tuner.
I figure I'll just keep it. I didn't pay a lot for it so, it doesn't seem worth the hassle to try and return it.
All well, problems for a different thread.
