[mythtv-users] strange watch recordings screen behavior

[scram69]

I'm seeing strange behavior navigating the Watch Recordings screen.
Using the up/down arrows to move through the recording groups takes a
very long time - moving to the next group takes ~15 seconds for the
shows in that group to become visible.  Checking the log, I find that
there are "FindRecordingFile" errors associated with each of the 6
shows visible when I navigate to any given recording group.  Sure
enough, these 6 sets of error messages take 15 seconds to generate.
An example:

Of course, each of these files is present on the Backend in precisely
the location where the frontend failed to find them!  The files play
fine, it just takes forever to navigate through the screen.  As you
can see, ~3 sec/show * 6 shows * 10 recording groups and I've spent 3
minutes just navigating to a show...

This behavior occurs regardless of theme...

Has anyone else seen these type of error messages?
