I have the HDC model. The little light emitters that come with the MCE and
hauppage blasters have such a short range I cut one off and soldered an IR
emitter, salvaged from an old remote, back in it's place. This works much
better with increased range. I have uncovered another issue though my
Samsung LCD is emitting IR interference. The blaster works flawlessly when
the TV is off, when it's on the blaster is completely unreliable.

I feel my safest option is to buy 6pin to 6pin firewire and use that.
