You can put in any username and no password it still works. It pops up wanting a username and password. This version of MP2Extended doesn't work properly when you turn off authentication. Previously with the Emby Mediaportal plugin (for MP1) I could only get it to work properly if authentication was turned off. I added in the updated streaming profiles and the 64bit version of ffmpeg (even though I use direct stream). The old version of MPExtended has been updated as MP2Extended: The old version for MP1 doesn't seem to work properly with newer versions of Kodi on RPi. I had to migrate to MP2 to sort out some issues I had with the TVServer/Kodi plugin. I assume then that once MP1 is installed, configured and running smoothly, then the EMBY plugin is all that is required? No special tweaking or additional components? I am encouraged by your comment that the engine is the same. I will restore that image and try MediaPortal 1.
I did a full image backup of my EMBY PC before installing MediaPortal2 as this was an experiment. It's my first look at MediaPortal and I was very impressed with the speed of channel switching and the better quality playback compared to NextPVR. Yes I am only interested in the TV aspect of MediaPortal as EMBY covers the rest very well and I want Emby Theater to remain the front end for access in the lounge. But then MediaPortal 2 will have its own webinterface, so need for Emby by this time. Maybe we get this by the end of the year. If for whatever reason you really want to use MediaPortal 2 as your main mediacenter and Emby just for mobile and remote watching/management of live tv, then you'll have to wait until the prerequisites are coded into MediaPortal 2. But again this is only possible with MediaPortal 1 right now. There's no connection between the two systems other than using. If you also want to use the MediaPortal frontend and video libraries, then i don't know how Emby comes into the game. The tv engine of MediaPortal 2 is the same, so no benefits there. If you just want to use the tv part of MediaPortal in either Emby or Kodi, then go with the standalone TVServer of MediaPortal 1.
