What was the exact command with which you ran it?
Apparently the directory has a file 'Some Video.mp4', which was not listed
in an existing checksum file.
I also noticed a problem recently which happens if you give dh a directory
as argument which has no checksum file in it. Or something like it, I can’t
reproduce it from memory right now. I have been doing some refactoring
recently in order to get one-file-per-tree mode working.

Yeah, using the -c option will clobber any old checksums and re-read all
files fresh. If you only changed a few files, using the -u option will
drastically increase speed because only the changed files will be read.
Use the -d option to clean up dangling entries from checksum files.

dh has some smarts built-in. If you changed a file, then its modification
timestamp will get udpated. When dh runs in -u mode and it finds a file
whose timestamp is newer than its associated checksum file, that means the
file may have been altered since the creation of that checksum. So dh will
re-hash the file and replace the checksum in the checksum file.

Me too, usually. If it’s not my software, anyways. ^^
But I think you may be the first other of that tool other than me.
