Hi Daitau,
As your card appears to be built to the phillips reference design, it is
possible that your card uses the I2C bus for the IR remote. Try running
the I2C detect program found in bttv-0.7.
Below is a quote from an earlier post by Gert Vervoort on this topic.

Schematics of the SAA7134 Philips reference boards show an i2c based
solution for the IR receiver IC. But it could also be possible that the
IR receiver IC is connected to the gpio of the SAA7134.
If you would scan which devices are available on the i2c bus, you could
see wheter an i2c based solution is available. In the bttv-0.7 package
there is a tool called "detect", which scan the i2c bus for devices.
Output for my bttv-card:
[root@viper tools]# /sbin/modprobe i2c-dev
[root@viper tools]# ./detect
0x30: Hauppauge IR (pic16c54 onboard)
0x80: msp34xx/tea6300 sound processor (error: Device or resource busy)
0xa0: eeprom (bt878, Hauppauge-848)
0xc2: tuner (error: Device or resource busy)
[root@viper tools]#
In case of a SAA7134, you will find a tuner (0xc0,0xc2), maybe an eeprom
(0xa0,0xa2,0xa4,....) and if there still one more i2c address left, it
is likely the IR receiver IC.
You could also have a look at the board, and see what IR receiver IC is
mounted on it.
The lirc package has a driver for a i2c based IR receiver, which works
for my bttv board.

Hi David,
After receiving your instruction, I enthusiastically tried it on my
board (card=1 (while banging my head on the wall, wondering why I didn't buy
a flyvideo3000 in the first place)). This basically gives the same result
with the last attachment you sent, i.e. no 'meaningful' values shown on the
gpio tracking line:
saa7134[0]: gpio: mode=0x0000000 in=0x0000000 out=0x0000000 [pre-init]
No matter how I press/hold the buttons on the remote control the values
do not change a bit. Does it mean I am out of luck for now?
By the way, anyone got this card other than me? Seems most of the
posters here got flyvideo and friends.
My config:
Mandrake 9.1 (2.4.21-0.13mdk)
saa7134-0.2.7
My card is:
00:0d.0 Multimedia controller: Philips Semiconductors SAA7134 (rev 01)
Subsystem: Philips Semiconductors: Unknown device 2001
This one looks exactly the same as the one shown here:

(My card is branded 'MIX' on the box with no other obvious/visible branding
on the actual card.)
Thanks in advance.
Daitau
