Recording file path isn't stored in the database--only a storage group
name, which is a logical identifier associated with a list of
directories.  Therefore, all the database can say is that a file
called--for example--"1201_20090509050000.mpg" exists in one of the
directories associated with <storage group name> /on the host/ hostname.

You cannot move recordings from one host to the other--unless the
filesystem to which you move the recording is available "locally" (i.e.
through NFS mount) to the original host and that network filesystem is
listed as one of the directories in one of your storage groups on the
original host.

If this isn't the case, you'll need to edit the recorded.hostname
field.  http://www.mythtv.org/wiki/Database_Backup_and_Restore

http://www.mythtv.org/wiki/Mythrename.pl#Basic_Usage (see the part about
resetting the names).  I /highly/ recommend doing so.
