Chipppy, I have this card working. As you found, you need to install the latest DVB-T drivers.https://help.ubuntu.com/community/DViCO_Dual_Digital_4http://www.linuxtv.org/wiki/index.php/How_to_build_from_Mercurialhttp://www.linuxtv.org/repo/
I am away from my LMCE machine where I have documented some of the steps I had to take.
How do you know the driver install worked OK? I think I found I had to download the firmware as well for the Rev 2 card, though the instructions say you don't.
I found your posts on the Ubuntu forum as well- if you do
ls -l /dev/dvb*
do you see the 2 adapters? /dev/dvb/adapter0 and /dev/dvb/adapter1
Be warned that to get this DVB-T card working properly, I had to do the following
1) Compile a new kernel (not as hard as it sounds) to get a reliable driver for the USB chip on the Dvico card
2) Compile and install the latest DVB-T drivers from the linuxtv web site (also not that hard)
3) Compile and install the LIRC modules for the remote control that I am using (mceusb2, Microsoft remote and USB receiver). Needed cos there was a new kernel.
4) Compile and install the latest nvidia drivers
If you don't do steps 1, 2, and 3 you may have an unreliable system. At least I did but that may be a combination of motherboard and the DVB tuner card. But if you do just step 2 and install the latest DVB-T driver on a standard LMCE 710 install you will at least get the card working to the point where you can see some TV programs, though your server may hang after a day or 2.
I used kaffeine to test the card, though you can also use mplayer and xine. I'll have to get my cheat sheet from home to help out more. Testing info herehttps://help.ubuntu.com/community/DViCO_Dual_Digital_4
Don't despair, once you get through these steps you will have learned a lot about LMCE and will also have a reliable working system!
PS I am also in Perth!
