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
are you on buzz 4 or 5? what buzz version number?
In buzz 5 there is an issue with recording from epg but all other ways work fine
On rare occasions there have been server/box conflicts and that has to be discussed in pm with allaboutbuzz
There is a beta update available for buzz 5
Home page check for updates
When it says no update available Type 2015 on remote If it says no beta available your mac will go on a list for next week
I would wait till then to troubleshoot issues
