How to install the Ceton Infiniti PCIe digital cable tuner card?

Question

Can someone give instructions "for dummies" on installing the Ceton Infiniti PCIe digital cable tuner card in Ubuntu 12.04?

Answer 1

I finally got this working, but I didn't (couldn't) use stock Ubuntu. I'm going to write up what I did, but I'm going to put it as an addendum to the official talk page on MythTV. You should be able to find it at the official page when I'm done.

Key Points:

• You need to get and build the drivers from Ceton. They don't come in Ubuntu 12.04 either as a kernel module or add-on code in apt. If you update your kernel, you will have to manually re-install the drivers.
• You need to make sure your computer speaks to 192.168.200.1 over the ctn0 interface. If you have no ctn0 interface, see the above bullet point.
• I couldn't get this to work in MythTV 0.25; I had to use MythBuntu's add-on package to upgrade me to MythTV 0.26. Then it worked.
• You can't search for channels. You'll need SchedulesDirect in the United States or something similar in your home country to get your appropriate channel list. If you have a channel list, not searching for channels is perfectly fine.
• You should use mplayer to test your CableCARD setup:

cat /dev/ceton/ctn91xx_mpeg0_0 | mplayer -cache 8192 -

Check out http://cetoncorp.com/infinitv_support/linux_drivers/. Note that Linux support is limited however due to CableCARD rules.
