[linux-dvb] Driver for digitalnow DNTV Live! Low Profile card

Replying to my own query from ages back so that others can find this
information a bit quicker. Hopefully Google will pick this up.
The digitalnow DNTV Live! card I was talking about is the low profile
PCI card. It is supported via the Conexant reference design drivers,
which they tell you on the specifications page for the card:
Under debian, this requires a minor tweak to modprobe to override the
autodetect of the card. The cx88 driver thinks the card is card 23,
which is a different digitalnow DNTV Live! card, but the low profile
card has same subsystem identifier, apparently. eg:
Sep 21 17:57:22 localhost kernel: cx88: subsystem: 17de:a8a6, board:
digitalnow DNTV Live! DVB-T [card=23,autodetected]
This is with kernel 18.104.22.168.
To fix this, you have to force cx88 to used card=19, which under debian
(and I believe Ubuntu) is done by adding a file to /etc/modprobe.d/. It
doesn't matter what filename you give to the file. The file should
contain a single line, thus:
options cx88xx card=19
Remove all the cx88 related modules with rmmod if you have any loaded.
Then, when you run
you should see this in dmesg output:
cx88: subsystem: 17de:a8a6, board: Conexant DVB-T reference design
You should see the following devices as well (assuming this is the first
or only DVB card in your system):
fnord:/dev/dvb/adapter0# ls -lart
drwxr-xr-x 3 root root 60 2005-09-23 15:26 ..

drwxr-xr-x 2 root root 120 2005-09-23 15:26 .
You can now proceed to run through the fun process of scanning for the
channels in your area and setting up channels, mythtv and whatever.
I haven't got my scanning working as yet, but I'll ask about that in a
Hope this helps someone.
