My 950 is behind a wood door, so I want to use the ir extender jack on the 950.

The manual is a little sparse on directions, just says to connect an optional remote sensor to the jack.

Where do I get an "optional remote sensor"? I hooked up the one that came with my TV, but that didn't work.

I have those Recotton ir transmitter/receiver pods, but I'd like to ditch them in favor of a little sensor.
