I think you got something mixed up here; CoreElec is an operating system, like Windows and Kodi is a (media center) program running on it, like the Windows Media Center running on Windows operating system.
So your question is similar to: I’d like to know what can we do with Windows that we cannot do with “Windows Media Center”. I don’t know of any meaningful answer to such a question…
Btw, Kodi Media Center (developed from XBMC X-Box Media Center) can run also on Windows, Android and other operating systems.
I’m sorry, but I’m not sure I understood your answer correctly. I may have formulated my question incorrectly
It seems to me that Corelec is a Kodi based OS. And much of the interface and functionality is similar to Kodi even though technically it’s an App and an OS. And so the fact that CoreElec is an operating system allows some things that are not possible on Kodi.
As an Android Box user, I am trying to find out what can be done with CoreElec.
There are a lot of people I think who use CoreElec as a Kodi mediacenter with the advantages of having HD audio, Netflix Full HD, better performance …
For me Windows and Windows Media Center are two very different things.
