I believe that both fields add useful functionality and don't want to drop
either of them. Somehow I like the idea of being able to set a guranteed
lifetime, no matter what else might happen.

You're right, I'll do that.

Once the lifetime has been exceeded, a recording can be erased by any
other recording, no matter what priority it has. If there is more than
one recording that has exceeded its lifetime, the one with the lowest
priority will be erased first.

Sounds reasonable. I would suggest to use the special value of 0 for the lifetime
parameter to control this. That way, if you always use Lifetime = 0 it would
behave as if that parameter didn't exist and deletion would be controlled only
through the Priority parameter. If you set Lifetime = [1..98] the
recording would get that guaranteed lifetime, and the special value of 99
would mean "unlimited" lifetime. Adding new Setup parameters for the default
lifetime and priority would complete this.
