Yes, it is the same path on the both FE and BE, the video files are
local on one FE and NFS mounted on the other FE and BE (but I guess it
does not matter that they are also visible on the BE).

At first the files were visible in mythvideo on both FEs, but after the
scan of the NFS FE they become invisible, a scan on the local FE found
them, but they stayed invisible on the NFS FE.
After I restored the videometadata table, the files are visible in
mythvideo on the local FE but not on the NFS FE.
