Hold power button down and select restart See if that message goes away
So pressing the home button on remote does nothing?
How did you get to settings?
if you have it set to external you need to use an external player like mx or vlc to play the video
your comment about having to reboot everytime to watch live tvis unclear Post some detail
there are two media players in menu for playback Have you ried them both
also try inserting a usb stick or dr sd card ,changing storage location to usb stick and see if it records to that
it looks like you have tried most everything It could be a bad download?
i might consider a reset but i would uninstall the ssd first
you could try that or wait for allaboutbuzz for more advice
If you do a reset leave the ssd out and just try recording to internal first
