Prolink Pixelview PlayTV Pro
Prolink's Pixelview PlayTV Pro is powerful analog TV card.
The card works well, however needs some tweaks in modprobe.conf to work properly.
Overview/Features
The device provides:
- TV support
- FM support
- remote control
Components Used
bttv for TV, FM and remote control support for LIRC.
ir-kbd-i2c to make LIRC support our remote control without special kernel module.

Making it Work
Firmware
Anything more than vanilla kernel provides is not required.
Drivers
Anything we should do, is modifying /etc/modprobe.conf (in Fedora it's almost empty, in SUSE messed "a little bit").
options bttv card=70 tuner=28 radio=1
Sample kernel output

According the output, support for the card seems to be broken, but at least FM and remote control works (currently I have no TV input in my room).
Remote Control Support
bttv with provided options and ir-kbd-i2c *MUST* be loaded before starting LIRC.
This can be easily done in Fedora and SUSE (didn't tested others).
Fedora
In Fedora you can edit /etc/rc.d/init.d/lirc
Add modprobe ir-kbd-i2c between start() { and echo -n $"Starting infrared remote control daemon ($prog): "
Add chmod 777 /dev/lircd between retval=$? and echo.
Fragment of /etc/rc.d/init.d/lic should look like this:
start() {
modprobe ir-kbd-i2c
echo -n $"Starting infrared remote control daemon ($prog): "
daemon $exec $LIRCD_OPTIONS
retval=$?
chmod 777 /dev/lircd
echo
status $prog >/dev/null 2>&1
if [ $? -eq 0 -a "$ENABLE_LIRCMD" = "yes" ] ; then
echo -n $"Starting infrared remote control mouse daemon ($prog2): "
daemon $exec2 $LIRCMD_OPTIONS
retval=$?
echo
fi
[ $retval -eq 0 ] && touch $lockfile
return $retval
}
Also, edit /etc/sysconfig/lirc:
LIRCD_OPTIONS="-H dev/input -d phys=pci-0000:00:0a.0/ir0"
Value after -d depends on output of one command:
$ cat /proc/bus/input/devices |grep ir P: Phys=pci-0000:00:0a.0/ir0
Change Phys to phys and copy.
SUSE
In SUSE you don't need to edit init scripts. Only /etc/sysconfig/lirc, simmiliar to Fedora's one, but they separated LIRC parameters and it's easier in SUSE. You can use sysconfig editor from YaST, but to get phys address, you need terminal.
LIRC configuration
As I wrote above, you have now basic configuration to make LIRC work, however LIRC doesn't recognize your buttons.
Here you go, your brand new /etc/lircd.conf ;) .
