Mine stopped doing this once I loaded: 2023.02.28.2326. However, it was crazy intermittent before, so maybe that was just a coincidence. Can't tell unless it comes back again.
I'm using the RB Pi 4b image DVR, along with a WD 4TB external powered drive. I started wondering if sometimes the drive shuts/spins down, yet the DVR still plays in the situation due to caching? Then when you EXIT, it has to wait until the drive spins all the way back UP, to confirm exit?
This is the drive I'm using, purchased from Amazon: WDBWLG0040HBK-NESN
