Thanks Mike. I can add that I have rules for recording I don't mind
getting deleted before watching. I just record those in case of. So I
set those to auto expire and some to max recordings (annoying by the
way that the default for max recording is to delete the latest and not
the oldest!) All other rules I have set to not auto expire and ones
every few weeks I check watched recordings that are allowed to expire
to auto expire.
So overall nothing unwatched can accidently gotten deleted by the
system. Only by my own dumb fault. ;-)
