HELP! Using IR/RF to control two cable boxes

I have figured out how to set up a system in my under-construction home, but keep coming up against it with regards to controlling things with a remote.

Basically, I can set up a server room that houses 2 identical DVR [cox HD dvrs or two tivos, whatever] on a 4x4 matrix switch, which should allow me to sit in my living room and choose which source feeds that tv, while my wife sits in another room and chooses the other source.

Here is the catch: Remotes for Cox cable boxes or tivos, are set so that one remote controls ANY box, meaning they aren't specifically tied to one box. So, even though I can direct the video [or control the video] to specific rooms in the house, and have different rooms watching different things, when I sit in that room and change something [channel, recording, etc] it will change it on both boxes.

Are there any IR/RF setups that solve this issue?

You wrote "An RF Extender requires the use of an RF remote. The RF remote...
...With most RF Extenders you can specify which port to emit the IR signal. With multiple ports you can have multiple of the same device. The IR signal will be routed to that device and not the other devices. This allows you to control multiples of the same device with a single remote."

And

When using the addressable emitter ports you can assign duplicate devices to separate ports and control them independently of each other. Since the emitters cover the IR receiver (you can further cover the receiver and emitter as needed with electrical tape or similar) you can eliminate bleed through of the IR signal. Doing this would allow you to control multiple identical TVs or cable boxes in a sports bar using a single remote. With an IR only remote the signal would likely be received by more than one TV.


So, if i am understanding this correctly, I can have three rooms with TVs, my duplicate cable boxes housed in a server room [with a matrix switch]. I then use an addressable RF base station in each of the rooms with the tvs, I then can control the two cable boxes independently from two different rooms [using the cable remotes that come with the box]?
