First off, here is my setup. I have a dedicated theater room with a AV closet outside the room. I use an RCA IR to RF (to IR) wireless extender which takes the IR from my Harmony 880 in the theater, converts to RF and the receiver in the AV Room receives the RF and converts it back to IR. I have the receiver connected to a block that has 6 IR blasters/emmitters plugged in and each taped to the front on my different devices (receiver, hd cablebox, DVD player). It works perfectly...that is it worked perfectly until I wanted to add a HTPC. I purchased an lite-on keyboard and IR receiver initially and it worked perfectly with Theater Tek to control the HTPC from the theater. At that point I decided to go with MCE and purchased the MCE remote, keyboard, and IR receiver. That's where the happy story ends. The RCA device does send a signal out from the Microsoft remote and/or keyboard and I see the Microsoft IR blasters that came with the setup flash bright red outside the theater when the keyboard or remote is used and I even see the M$ receiver flash as it receives the signal...yet nothing happens on the HTPC. If I go outside the theater and aim the keyboard at distance right at the IR receiver, MCE controls perfectly. Via the RCA ir to rf to ir extender...it doesn't work.

My guess is that something gets 'lost in translation' and the IR code that the RCA device spits out isn't being recognized by the Microsoft IR receiver.

Anyway, I wanted to get some input as to what the problem is and what I can do to get it working. Can I run a wire with some sort of small receiver and flasher on the other end that will work with the MCE receiver?
