How Can I take full resolution Screeshot of playing services or any DVB channels, I try with Corus, but only produced pic in distorted image, Is there any restriction ? because, with out playing media, its perfect pic for UI. I have WP2 running on latest Coreelec build

With a keyboard pressing Ctrl+S should take SS in Kodi, did you try that method also?

I got SS, but it creepy, not a good pic captured, it must be few hundred KB, but, only 30 kb
