Hi,
I recently migrated my master backend from one system to a new one.
Everything seems to be peachy (recordings, viewing, music, etc.), except
that it doesn't seem to be able to create the preview pixmaps for
programs recorded on the old backend, or on remote backends.
For files recorded before I migrated the backend, I see the following
backend logs:

I did hack into the DB and tried setting the hostname in the recorded
table to my backend's new hostname from the old hostname
(codeine=>phoenix). That got different results for the old files:

For the files that have a hostname of my remote backend/frontend (myth),
it doesn't even seem to try to create the pixmaps. I've checked file
permissions on the directories (/export/mythtv has 0777 permissions), so
I think that it's not that simple a problem.
Has anyone seen issues with creating the preview images before?
Thanks,
Jason
