Is it possible

To stat a recording that is in progress from the beginning?

Do you mean, is it possible to start watching from the beginning a recording that is still in progress?

Unless it’s changed recently, no.

Yes, that’s what I mean.

Thanks for the info.

Devs, this should be a thing.

this is NOW a thing! Released last week:

(Live) Added the ability to seek within an active recording, with client support (#7270)

Yes! However, key words are “…with client support”.
It works great on my NVIDIA Shield TV but it is not (yet) available on my Roku (Stick or Première +)
