I own both Beelink, 16 & 32 Gb version.
Both working fine at 4k and HDR
But I´m running LE from SD card, there is no advantage installing internal
I own a Beelink 32 GB version and I agree.
Also, there is indeed no advantage in installing it on external.
I did once because android annoyed me but that situation has been reversed.
BobFlyer The remote.conf is for the included remote.
You can approach the SMB folders in libreelec by using the windows run box [windows key+ r] and type \\libreelec\
if it's in your network. There's a folder called config (or config files) in which you can just past the remote.conf.
If there already is a remote.conf make a back-up. That's all I have for you. Good luck.
