[mythtv-users] MythWeb (0.19) listing much slower than frontend

You may have a problem I have just solved.

Mythweb goes and checks all the icons (thumbs) for the programs and 
generates them if they are not there. It retries each operation for a 
while if the mpg / nuv is invalid or absent.

Look in /var/log/mythtv/mythbackend.log to see whats going on. I saw 
lots of invalid files.

The reason was there were several nuvs with 0 file size created while I 
was messing with the system during upgrade.

In addition I had changed the hostname for the 0.19 box and the old 
recordings were under the old hostname in the database.

Hope this helps :)

I saw errors similar to:
