Hi Mike,

I have the Joe Kane Samsung A800B DLP projector. Inside the cabinet is where the MRF-260 sits right next to the HDMI cables and the HDMI matrix. I use the blaster to control the Matrix, lighting, and Roku. They are all stacked up inside the cabinet facing the MRF-260.

Once I turned on the projector the RF commands on the remote stopped working. After the movie was over I was able to use the MX-450 to turn off the projector via ir, then as soon as it was off I had fully functioning RF again.

I just bought some ferrite filters at Radio Shack to see if that will help.

thanks,
~Jay
