The "total <blargh>" lines in a long directory listing do not
report the number of files in a directory.  Rather, they report
the total disk allocation (i.e., the number of blocks) for all
files in that directory.

If you know the name of one of the files, you should be able to
find it with the find(1) command.  cd to /media and try

    find . -name movie_name -print

If <movie_name> is excessively long, or you don't remember all of
it, use a wildcard like \* at one end or the other.  E.g., "Star
Trek\*" (w/o the quotes, natch) should find anything Star Trekish.

Another thing you might do is cd to / and run the following
command:

    du -hl --sync --output=source,itotal,iused,iavail

This will list all your filesystems and display the total number
of inodes, the number of inodes used, and the number if inodes
available.  You may not be running out of inodes, but it's good to
check, just in case.

Hope this helps.
