The start playing time could be a hard drive that has to
spin up. You<br>
can use hdparm to see the state of a drive:<br>
<br>
root@mypvr:~# hdparm -C /dev/disk/by-label/rec1<br>
<br>
/dev/disk/by-label/rec1:<br>
drive state is: active/idle<br>
root@mypvr:~# hdparm -C /dev/disk/by-label/vid3<br>
<br>
/dev/disk/by-label/vid3:<br>
drive state is: standby<br>
<br>
I have never met your long timeout to exit "Watch
Recordings", but I<br>
am still using 16.04 with v29.<br>

I don't know about the long delay when exiting Watch Recordings, but
I have experienced long delays in starting a recording playback.
Over time, this delay would get longer and longer. What I found
that seems to help is the optimize_mythdb.pl script
(<a class="moz-txt-link-freetext" href="https://www.mythtv.org/wiki/Optimize_mythdb.pl">https://www.mythtv.org/wiki/Optimize_mythdb.pl</a>).<br>
