Since we don't know what exact encoding does it use... Can you test with
the attached patch? You have to add/substitute your card ID in place of
AVERMEDIA_SUPER_007 and "modprobe saa7134 gpio_tracking=1".

Press a single RC button.

It should produce a lot of messages like:
$ dmesg | grep GPIO:

If you send all of that to me I should be able to figure out the code used.
