So.. couple of weeks later, the card arrived, and I have some time to
play with it.

Note that I'm running latest stable Ubuntu 64-bit with kernel 3.0.0-16-generic.

First I tried the drivers from
http://linuxtv.org/hg/~endriss/media_build_experimental/. In that
case, dmesg output is:

[   11.728370] WARNING: You are using an experimental version of the
media stack.
[   11.728372]  As the driver is backported to an older kernel, it doesn't offer

So I started to try the build instructions found here:

http://linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers

And after compile, install and a reboot, dmesg output is:

lsmod shows that ddbridge and dvb_core are loaded. /dev/ddbrigde/card0
is created. My webcam is available as a device below /dev/v4l/, but no
entries exist for the tv-tuner card.

I can manually load cxd2820r, which loads succesfully, but has no effect.

Which driver should be used?

Any hints are grealy appreciated!

Martin
