Magic eye problem coming to your home soon

I have a 3 box set up which pipes the sky output to all of my TV sets. Each sky box can be controlled separately from any TV. ( using a TVlink SPC4 & T140)

so far so good.

I went TV shopping today and found that the analogue tuner is beginning to disappear. That means that magic eyes, which rely on analogue signals, will be useless.....
....unless someone knows of a workaround.
