Actually, as this is a DIY forum, perhaps one should attempt
to tackle a homebrew device to replace all the remote controllers,
TV, Freeview PVR, Freesat PVR and Tosh VHS/DVD PVR in one control box?

My Logitech universal remote controls the TV, PVR, DVD and hifi, with
scope for more. (DIY insofar as it needs connecting to the Logitech
website to be configured and for mapping buttons.)

There's nothing "clever" about the IR signals that control your TV (or
whatever)

All they are are a binary code transmitted at some specific frequency or
combination of frequencies

Any IR transmitter is going to be capable of morphing the signals required
by any TV (etc)

the hard part here is in creating a user friendly way for the remote to
learn what the codes are (and assigning that code to a specific button)

and that's where these products fail.
