Thank Littlesat,
Your procedure that the audio zap between the video screen.
That's not what I'm looking
But, this is not same comportement that plugin audiopip.
Because it is not possible to watch full-screen video and listen to audio of another chain.
This in concret example :
Euronews is multilanguage and SD video mode.
Surprise.. today they are new broadcoast => EURONEWS ENGLISH HD (13e 11565H sr 29900 dvb-s2)
This audio only English, but i'm not is perfect because i don't speak English
I would like watching this HD video mode in full screen and simultaneously listen to the audio from another French broadcast euronews SD
