This tv (sub) is not 3D capable

Why do you think this comes from Kodi? I haven’t found any string like that in the language ressources.

But … from the logs I see an Onkyo AVR the Vero is connected to … and with that giving the message it makes a lot more sense.

So what happens of you hit “OK/Enter” on the Onkoy’s remote control seeing this message?

I don’t have any 3D display but this is what I see when I set the option ‘Ask me’

Then if I Select alternate mode I get

@jcf6288 so if you either choose on first Screen “Monoscopic/2D” or “Disabled” on second should give you 2D playback and the warning of your AVR should not be displayed.

I is coming from my AVR which is weird. It works find now. Thanks for all the help.
