Hi Edward,
Yes its running 7.9.4
Previously when naming playbacks they have remained after powering off the console. Some of the original playback names still remain, but any recent ones just vanish, with the exception of two playbacks I named yesterday which do remain, however if I try and change one of these then the changes aren't saved.
Saw an error, co processor is missing during boot up ? That normal ? was highlighted in red on the external screen.
Ok, so entering setup and exiting setup, this did seem to save the name on the playback, however as I'm writing this and testing it, the console ( maybe related to the error above ) won't show any page numbers, cannot select anything either so looks a bit stuck !
