Hello Copernicus!
I'd like to share some user experience with you. I've got two old CRT Samsung TVs. And mostly, the TV keyset one works well. But, I am able to select AV as an input source, but unable to revert back to coaxial antenna.
Also I'm able to use teletext, but unable to go back to TV. On the original remote controllers, it's the same button. Pressing txt button only changes the backgroung from black to transparent.
Can you do anything?
Also, I see you've added air conditioners. Please add a Thomson keyset if you can.
Thank you for your great app!
(I've got a Thomson universal remote controller too, and it's able to switch between tv/av.)
