Yes, this is most likely the issue. The hash that's created to identify
unique videos is done with only a small part of the file at the
beginning and the end (because reading multiple gigabytes per file from
disk and running the entire video through a hash algorithm would take
ages to complete). It's likely your test files are just too close to
the same, so are being considered the same and only showed once (one or
the other is shown and the one not shown is ignored).
There's no way to "fix" this as it's working as designed (and typical
use cases don't involve multiple almost identical files). So, you can
rotate them in and out to see them all. Note, too, that the title of
the video shown is not necessarily the name of the file being
played--you'd have to look at the filename in the detailed metadata
screen to know for sure which you're playing--and if you swap files the
new file may show with the same title, even though it would now play the
You may be able to work around this by creating test encodes of
differing lengths/portions of the video.
