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: http://www.digitalnow.com.au/product_pages/dntvlp.html 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[0]: subsystem: 17de:a8a6, board: digitalnow DNTV Live! DVB-T [card=23,autodetected] This is with kernel 2.6.12.1. 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 modprobe cx88-dvb you should see this in dmesg output: cx88[0]: subsystem: 17de:a8a6, board: Conexant DVB-T reference design [card=19,insmod option] 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 total 0 drwxr-xr-x 3 root root 60 2005-09-23 15:26 .. crw-rw---- 1 root video 212, 3 2005-09-23 15:26 frontend0 crw-rw---- 1 root video 212, 4 2005-09-23 15:26 demux0 crw-rw---- 1 root video 212, 5 2005-09-23 15:26 dvr0 crw-rw---- 1 root video 212, 7 2005-09-23 15:26 net0 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 separate email. Hope this helps someone.
