Ubuntu doesn’t immediately recognize this card for some reason. There are many ways mentioned on the internet on how to fix this, however I found what I believe to be the simplest fix.

Perform the following before entering MythTV setup. If you are installing Ubuntu first and then MythTV then simply do this during your hardware enable stage before the MythTV install (note that it is better to install Nvidia/ATI graphics card drivers AFTER the MythTV install). If you are using Mythbuntu, do not perform setup and click Finish at the end of your install. Reboot and load a different run-time so you can use a console to perform these instructions. Then switch back to the normal run-time and go ahead and continue the setup. To switch run-times type ctrl-alt-f4 (or other function key). The normal run-time is on ctrl-alt-f7. NOTE: I’m not familiar with run-times so use at your own risk or use a different run-time according to your knowledge. Let me know if ctrl-alt-f4 is a bad one to use for this.

If you’ve already setup MythTV then don’t worry. Use the run-time trick mentioned above or just boot into Gnome and then rerun MythTV setup. Correct the capture card, video input, etc.

Sudo edit /etc/modprobe.d/options and add the following line at the bottom:

options cx88xx card=4

Then perform the following to enable it:

sudo modprobe -r cx8800

sudo modprobe cx8800

Then use dmesg to check it. It will be towards the bottom so just typing dmesg and hitting enter at your prompt is sufficient. If it worked the brand (TV Wonder Pro) should show up somewhere around the messages regarding the tuner card, and there shouldn’t be an error towards the end.

I give credit to this fix to someone else, but I don’t have the link. If I can find it again I will post it.
