Show recording has start stop when possible but can't change

[denz 501]

Just happened to go a detail screen of a recording in progress and noticed it has start when possible and stop when possible so assumed you can extend the recording so tried putting a number in but it doesn't save it. So not sure what is the point of having it as an editable field.

Hi, the start shouldn't be there if it's already started, so that needs adjustment.

Changing it during the recording hasn't been implemented yet.
