[mythtv-users] Performance regression after upgrade to 0.26

Hello all.

I recently upgraded my systems to 0.26 (version info below), and I
noticed the following performance regression:

There is a long delay (tens of seconds) but of varying duration when
beginning or resuming playback of a recording which is still in
progress. There is nothing in top that I can see when this happens,
except that there is ample CPU and memory headroom, both on the frontend
and the backend.

Does this ring any bells for anyone?

Many thanks, Jan
