I have got the audio and video on my AV distribution network DIY upgrade up and running but am having problems figuring our what to do with IR controls.

I am distributing HDMI from four sources (Oppo BDP, DirecTV HMC, DirecTV HDDVR, Security DVR) through an Octava 4x4 HDMI matrix to four zones (3 over CAT5e using Altona HDMI Extenders and 1 wireless using Iogear Kit).

Two of the sources (Oppo, DTV HMC) and the Octava have direct IR input ports which I would like to use in lieu of stick on emitters. The Altonas have bidirectional IR and the Iogear has unidirectional IR. I also have Universal Remote RF/IR remotes communicating with a base station from the original installation.

I bought a bunch of 2.5 and 3.5 mm stereo cables and have tried a couple of obvious setups and they have given me erratic results. I have tried using the UR's and outputting from the the UR base station to the sources direct and through emitters. I have also disconnected the UR's and gone strictly with IR through the extenders. I also have tried a high power IR blaster in lieu of multiple emitters. Only a fraction of the signals seem to get to the DirecTV boxes and not in any consistent way. The Oppo responds consistently. The Security DVR not at all.

I thought maybe the problem was incompatible cables (2 vs 3 conducter, mono vs stereo) but the device manuals have no specific info on this and could not find much helpful in searching this site.

My eventual plan is to use a Xantech 4 zone IR distribution block to consolidate and distribute IR signals in the rack and a Globalcache GC-100 IP-IR network adapter so I can switch from RF/IR remotes to Iphone/Ipads over IP. I have these two devices but don't want to dive into connecting them until I figure out the compatibility issues....

Any suggestions would be greatly appreciated...

I don't have many answers, but I've struggled with this as well. Just a few comments about my experience. You might have problems going between mono and stereo connections when using adapters. It's not about the mono or stereo; I think the connection just ends up on a "dead end" leg sometimes and may require a reversal of the wiring. I needed to run IR over a coax cable and did that successfully with 3.5mm to RCA to F-Connector on one end and reversed that on the other. Using a continuity tester will help prevent some frustration. I've also run a cable from my IR blaster (Monster/Logitech) to receiver (Pioneer) and it works well. I would avoid testing with DirecTV since those receivers lag so badly, it's hard to tell if it's the receiver or the control signals that are the problem.

For the DirecTV boxes if you're going the iPod/iPad route, ditch IR altogether and just use network/IP control. Works great, and yes, the D* boxes are very sensitive about their IR...

Similar answer for the Oppo - it's got full RS232 control that you can use with the Global Cache product. I've got all of the above working very reliably in my setup...

On the IR emitter / input wiring - you'll have to get the wiring diagrams to figure these out for sure. And yes, its very frustrating trying to use those inputs.
