There are 2 versions of this card, version 'I' & version 'J'. According various forums, version 'I' works out of the box, yet the later version 'J' needs some tinkering. Apparently version J was made to be compatible with Vista, so if you can avoid the box thats says Vista ready!

Version J Setup

Although this card does not work out of the box with a little tinkering you can quite easily get the Digital tuner to work in LinuxMCE. There is a patch available to get both the analogue and digital tuners but it looked a little too complex for my liking. http://lkml.org/lkml/2008/2/6/289 This patch is broken with kernel 2.6.25 diff -Naur /usr/src/linux/drivers/media/video/cx88/cx88-mpeg.c /usr/src/linux/drivers/media/video/cx88-patched/cx88-mpeg.c --- /usr/src/linux/drivers/media/video/cx88/cx88-mpeg.c 2007-10-09 22:31:38.000000000 +0200 +++ /usr/src/linux/drivers/media/video/cx88-patched/cx88-mpeg.c 2008-01-07 23:28:29.000000000 +0100 @@ -93,6 +93,7 @@

+ if ((core->board) == CX88_BOARD_WINFAST_DTV2000H_2) cx_write(MO_GP0_IO, 0x00017300);/*switch signal input to antena*/ gives an error (invalid binary assignment)

I succeeded in getting the patched code to compile by changing:

+	if ((core->board)

to

+	if ((core->boardnr)

but it still only gives me analog tv without sound

Anyway, to get the digital tuner to work you will need to follow 3 simple steps:

1. Configure linux to load the module cx88-dvb automatically on start-up using the command: sudo echo "cx88-dvb" >> /etc/modules This will add the line cx88-dvb to the file /etc/modules.

2. Edit the /etc/modprobe.d/options file and add the line: options cx88xx card=51 (card number 51 has been allocated to a different card recently, not sure if it is official but 68 was mentioned somewhere as appropriate)

This will tell mythtv exactly what type of card you are using.

3. In Mythtv-setup, under capture cards, select 'DVB DTV capture card (v3.x)' for the card type. Set 'DVB Card Number' to 0 ( for the first card, 1 for 2nd card etc)
