The card isn't natively supported in linuxMCE, but i'm guessing it should work setting it up in mythtv.
I think kubuntu 0710 lacks the driver for it so you have to download the video4linux drivers and install them ->
sudo apt-get install mercurial
hg clone
http://linuxtv.org/hg/v4l-dvbcd v4l-dvb
sudo apt-get install ncurses-dev
sudo make menuconfig
make
sudo make install
sudo nano /etc/modprobe.d/options
<then add:>
options saa7134 card=65 tuner=54
<then>
sudo make load
reboot and enter the mythtv setup from the computing tab of your orbiter; choose capture cards and see if yours is listed.
I'm guess that the remote will be difficult to set up. Best buy a seperate one, like the MCE remote and usb transceiver.
The saa7134 module is already installed nut not loaded by default;
lsmod | grep saa* <return>
dcerouter_66616:~# lsmod | grep saa*
cpufreq_powersave 3072 0
sata_nv 24068 0
libata 138928 2 sata_nv,ata_generic
The above line will find any modules currently loaded that start with 'saa'... you will probably get none returned. So do this;
sudo modprobe saa7134 <return>
dcerouter_66616:~# modprobe saa7134
Now do the lsmod line again;
lsmod | grep saa* <return>
and you should see something like this;
dcerouter_:~# lsmod | grep saa*
