The start playing time could be a hard drive that has to spin up.  You
can use hdparm to see the state of a drive:

root at mypvr:~# hdparm -C /dev/disk/by-label/rec1

/dev/disk/by-label/rec1:
 drive state is:  active/idle
root at mypvr:~# hdparm -C /dev/disk/by-label/vid3

/dev/disk/by-label/vid3:
 drive state is:  standby

I have never met your long timeout to exit "Watch Recordings", but I
am still using 16.04 with v29.
