Thank you for your answer..
that's the weird thing, I've tried multiple versions..
(official/pivos/nightly/with so called usb support/older pivos version which should work..etc).
Even with a usb stick 720p doesn't play ok with MXplayer.. original player is better.. but ok.. which XBMC version to use.....?
I've read that some people have use a build that you made (or how do you call it)..
but I don't know if my stick is exactly the same.. (smart tv stick (with different remote) or A22 or my ST-M3??) and I'm afraid to brick it.. (My supplyer is just someone who bought it and resold it (new) to me.. ) :
Smart TV Stick - J1nx .:Hackable Gadgets:.
In the reviews section they talk about different firmware builds, including yours.. and my stick looks the same.. but I don't know if it is...or isn't. (And it doesn't have a flash button..).
Or maybe I should just leave the firmware and find a different XBMC, don't know which one..
About the ethernet.. It came with an adapter (usb) and the 'leaflet' it came with, shows that you can select ethernet in the settings... but it's not there!
