SOLVED: Video playback in slow-mo

[MrFabou]

What I did: Reset CC ~ same behaviour
using the LG Store Version directly on my LG Smart TV: client error

the only option I got here is testing it on my old cc (the black one, 2. gen I guess)

Just want to make sure we are talking about the same Chromecast.

You're talking about this one, right?  The 4K model?

Yes, thats my CC that i'm using the most. 

I said that I could try using this, since I got it laying around:
