Making it Work

Firmware

No firmware is needed for ATSC/QAM functionality.

Drivers

The cx23885 driver has been upstream since 2.6.27, so should be available in some newer distribution kernels.

Otherwise, get the latest cx18 driver. Then, inside the cx18- directory do

make

and

make install 

as root. Then load the module

/sbin/modprobe cx23885


Known issues

If you are using Suse 10.3, on some systems it will hang on dvbscan as soon as it finds a signal.
If you encounter this issue, compile and install the 2.4.24-3 kernel.
Then recompiling the cx18 against it to fix the issue.

Remote Control Support

The IR Remote is controlled through the cx23885 chip, which is currently not supported in the driver

Testing

use scan to get the initial channel list required by [azap]

use azap to tune to the desired channel

use mplayer to watch the channel. Be sure to copy the channels.conf file from the initial scan to your ~/.mplayer directory

mplayer dvb://"Channel Name"
