[mythtv-users] Problems getting Nebula card to work

[Paul Volkaerts]

Hi,

I hope you can point me in the right direction here; I have a Nebula DigiTV
card that I am trying to get working with Mythtv.

I have the drivers installed as per the README with V4L2 etc and I'm running
driver 0.9.12 with linux 2.4.23.  The modules look like they are loaded
right but when Myth opens the /dev/video device it reports no input
channels.

I confirmed this just by running gqcam, which also reports the capture card
opens ok but has zero input channels; as opposed to my webcam on /dev/video1
which has one input channel.

Below are dumps from lsmod and dmesg --- any pointers will be GREATLY
appreciated and will make my New Years Eve all the better!!!

By the way, I am unsure if I am meant to load the kernel module for BT848
sound. It didn't load when I tried, results also below in case this is the
root cause.
