use the lmce directory structure, and make a symlink from a folder called tv_shows_1 on that disk, to /home/public/data/videos/tv_shows_1
please be sure to do this outside of the directory structure on the managed disk. DO NOT MESS WITH MOUNTS IN LINUXMCE. You will crash the system. The system has an extensive automounter system that will detect and mount all filesystems it finds.
i.e. say the disk is device 69
make a folder on /mnt/device/69 called tv_shows_1
then ln -s that to /home/public/data/videos
y'know I had tried this, and I found that the link was being deleted and remade as a directory entry. So, I just assumed that one of the automation scripts really wanted the tv_shows_1 to be a directory, and started doing things differently.
