Oh dear... whoever told you that piece of misinformation?

No. That link is for an IR *blaster*, which is used for controlling
devices like set top boxes. You would need to use an IR *receiver* if
you want your system to respond to a remote control, as you describe.

Again, you'll never get any response from pointing a remote control at
an IR blaster in irw.

You need to buy one of these:

http://www.irblaster.info/receiver.html

and use the lirc_serial driver with that, coupled with the Hauppauge
lircd.conf file for your remote control. Note that you would use the
lirc_serial module for either device though (serial IR
receiver/blaster).
