For the sake of the list ... I ended up changing both machines mythtv
UID and GID's to 113 (arbitrarily chosen from the unused UID/GID
available) by editing the /etc/passwd and /etc/group files for the
mythtv user and group. Then, ran the following command to find all of
the files orphaned by the change I found on a Debian Security
find / -path /proc -prune -o -nouser -o -nogroup
and then took the list of files returned and used chown appropriately
to reassign ownership.
