[mythtv-users] IVTV stops working, can't use test_ioctl?

[rob.parkhill at shaw.ca]

Just wondering if anyone has seen this problem before.

I had my PVR-250 up and running on RH9, kernel 2.4.20-8 by compiling IVTV from the latest CVS tarball (copying the videodev2.h file over.) Everything was working great, and I made a few test captures.

But after a reboot, I can't make recordings anymore. When I try to set the video input using test_ioctl, I get:

    # /usr/lib/ivtv/test_ioctl -p 6
    ioctl: VIDIOC_S_INPUT
    ioctl: VIDIOC_S_INPUT failed

When I try to capture some video with "cat /dev/video0 > temp.mpg", the command immediately returns with no errors, and I get a 0 byte test.mpg file.

/dev/video0 exists, and lspci shows that the PVR-250 is being recognized properly.

The only slight wierdness is from dmesg:

i2c-core.o: adapter unregistered: ivtv i2c driver #0

I've also tries using axboe's ivtv driver, but I see the exact same behavior.

Searching the ivtv mailing lists turns up nothing.

Anyone have any ideas where to go from here?

thanks...
