As I read what you've responded it's becoming clear that I misinformed you.
>From poking around in the BE setup storage directories, they are all
pointing to /var/lib/mythtv, the symlink my son setup for me was in my home
directory (on the precise system) to the mythtv directory (so I could
easily manipulate recordings) so becuse of the fstab editing, I assume, the
two 1Tb drives present themselves as "/media/storage" and "/media/storage2"
(when I hover on them after launching files), but /media/storage only has
two directories in it, mythtv ( this including the metadata directories
(banners, coverart, fanart, screenshots, trailers) and video and livetv.)
and forever (which I will remove) so now I would create a directory in
/media/storage2 called "recordings"? In /media/storage there is mythtv with
recordings in it, so I would have two recordings directories?
"/media/storage/mythtv/recordings" and "/media/storage2/recordings" or
should it be "/media/storage2/mythtv/recordings"?    as always, much
appreciated    Daryl
