Thanks for the feedback, everyone; I'll post updated version in a couple of days.
I'm a little surprised that it actually works on LN* models and CI+ models

. Good to know; it looks like SdVideo_Settings_t structure is well preserved in different firmware branches.

Wow, that will be nice thing to have.. but quite a challenge; it may be well above my skill level. Are there any known methods for checking current TV input source and tv channel ?

That's strange; remote control should just return to the "normal" behaviour after exiting resize mode (single <blue> keypress).
@msurg, @arris69:

Frankly, I don't quite understand what are you guys talking about

.. I guess it's about some method for installing content library apps in TV models without Game menu (???).

On "to do list" allready, should be implemented in the next version.
