Live TV stops playing at same time recording ends

Hi, I just saw noticed this happening again. I am pretty sure this went away, but I can’t say this was the first time since last year.

My question is when a recording is happening on a channel using a tuner and then that channel wants to be watched live… What tuner is used? The same one as the one doing recording or is a separate tuner?

I feel that it should be a separate tuner or maybe have this be an option in settings to use the same or different. With us having a 4 tuner odds are pretty slim that all will be needed at a the same time.
