I now never turn it off, or even put it on stand-by. If I do, it resets everything - including the screen ratio and loses my favourites list and recording schedule.
Unfortunately, it periodically decides to reboot itself - powers down briefly (all by itself) and reloads the software - with the same result.
I am now quite adept at sorting my favourite channels every couple of weeks, but this is incredibly irritating - so I wonder if anyone else has experienced this - and perhaps found a solution.
I have seen numerous posts which speak of restoring the machine to factory settings - but I can't find this option in the menu - only the 'reformat HD' option - which isn't what I want to do, as I have about 250gb of programs saved.
It seems to me, though, that it is restoring itself to the default settings every time it powers down - so I don't think this is going to be a solution anyway.
Apologies if this has been discussed before - I did search the forum, but I'm new here, so perhaps don't know what I'm looking for.
