Sorry!!!
I assumed it, (the Buzz app), allowed choosing an external video player, (like STB Emu, whSmarters, Kodi, and most other apps).
After digging deeper, I cannot find any info on how to do it.
Buzz uses the ijkplayer, which interfaces with ffmpeg, as far as i can tell.
My apologies!
MX Player is a great player for any video you have, so it is not a waste of time.
I don't have a Buzz available to play with at this time, but normally you would have to select which Player you want to use as an alternate (ie; If VLC and MX are available to use, app needs to be set).
Ex: with STBemu, you set app to use external player, then select from a list. (if I remember correctly!)
*Actually, this Internal or Secondary confuses me?
It keeps referring to the Buzz tv 2 app if you choose internal or secondary player there’s no way to change that I can see!!
Tired everything
Unless you know different?!
Same just one option Buzz tv 2 popped up to choose from
