Dear OP,

You might like to look into the archives for my earlier comments
regarding IR disturbances. Some monitors and TV sets produce enough IR
on their own that you might as well give up using an infra red remote
control. All my monitors and TVs fall into that category. It just so
happens that the TV's own remote control protocol is transmitted in the
blanks between the IR flashes given off by the back light. I couldn't
find another remote control which would transmit in these bursts. I
even bought a Sharp IR receiver chip to go with my Sharp TV and that
didn't work. It took me weeks of trials before I eventually gave up.

I settled on a Bluetooth remote control which I ordered from Maplin.
This has been flawless. They are coded so it is possible to have
several in one building without them conflicting. You just plug it in
and it comes up as a HID input device (a keyboard and mouse). No
drivers, no nothing. I have the key mappings if you want them.

Cheers,

Mike.
