If you're just going through one wall, I would go with a wired IR extender
This setup will have:
- an IR receiver eye that's mounted to the back of the TV (signals bounce off the wall and are picked up by the very sensitive eye)
- a confirmation LED that's mounted to the bottom of the TV. This flashes blue when the IR signal is received.
- Wire through the wall to the distribution box
- Blasters from the distribution box connected to each of the components
- All control done with a Logitech Harmony remote of your choice
I have the Hot-Link XL (IR over Cat5) and it works very well. You can do the pro though as its only a short run. The eye is very sensitive and there is no delay in transmitting the signal to the components.
The Harmony remote will allow you to set up activities macros for all of your viewing options and will automate the setup and customisations for each (e.g. press a button for watch TV and it will turn on the TV, AV receiver, go to the correct input etc). This makes the system much easier to use for the wife and kids and cuts down on remote clutter.
