Eduarxox,
thx for your feedback.
Regarding the JellyFish demos, have also a look here: Lost 2160p on vero after update - #8 by sam_nazarko
For me the statement regarding the remote control is more astonishing: The shipped OSMC remote controls are RF devices, so you don’t have to point in any specific direction. Also from my experience the reaction time for the RF remotes is much faster than any IR device.
Could you try a re-pairing of the OSMC with the RF receiver which is described here: Pairing the Original Black OSMC RF Remote Control with a Pi/Vero2/4k/4k+
