I used Redeye to control my AV equipment and discovered that while it works, my family are hard-wired to use the Tivo remote over an iPad or iPhone to control the TV.
Rather than fight this, I want to convert my Tivo remote into a universal remote and use the function buttons as inputs to an IRLinc Receiver, then convert that to Insteon, send back to an IRLinc Transmitter to control the other AV equipment.
This seems like a long way for a short cut and I wondered if anyone knew of a way to use the built-in IR receiver on the IRLinc Transmitter as a receiver which could then be converted to output IR without going all the way through Insteon.

I don't believe so.

The IR-Linc devices, in our experience, are difficult to use and manage. The Global Cache devices, while more expensive, have plugins available for Indigo so managing and using them is much easier. Also, using INSTEON as the bridge between the remote control and the devices being controlled is probably not going to make for very good realiability and response times. I think I'd take a good long look at what your needs really are, without any regard to existing HA equipment, and then look for the best solutions.

The EZIRT (or something like that, the one the sends and revives) can be used a a repeater. I'm doing that now. I don't think I needed to set anything for that to work.

Turns out it was even easier than I thought.
Tivo supports learning and 2 separate DVR code sets so it was pretty easy to configure the system using the Tivo remote control.
In the interests of completeness on the off chance anyone should be interested in the details read on. For the rest of you, you can stop reading here.

System has a Panasonic TV with a Panasonic surround-sound system connected to HDMI port 2 of the TV.
HDMI port 1 is connected to an HDMI switch with with I use 2 inputs. Switch input 1 is Tivo and switch input 2 is Apple TV.

Use this link you configure the Tivo remote to control the TV and surround sound volume

Use this link to configure the Tivo and remote to support 2 DVRs which you need to have the remote map DVR1 to Tivo and DVR2 to Apple TV

On Apple TV go to Settings->General->Remotes to set up and learn a new remote with the Tivo Remote set to DVR2.

That's all there is to it - total cost $0.

Now all I have to do is sell my stupid RedEye on Ebay

Forgot to add.
Use the following link to configure the Input button on the Tivo remote to learn the "next" button on the HDMI switch remote. With only 2 HDMI channels, the Input button will act like a toggle select between Tivo and Apple TV
