Pluto TV SF 6250 (and older): Several Lupin III Movies Failing on Remux

[BradYonder]

Quite some time ago I noticed that a handful of Lupin III movies were failing during remux on Pluto TV. Had more important things to worry about at the time so I put it on the back burner.

Today I re-visited it with SF 6250 and noticed the problem was still there, so I thought I'd bring it up.

I already submitted feedback through the app but am posting it here as well in case anyone else had (or is having) the same problem.

These movies are being downloaded as "tv episodes" even though they are individual movies, and not all of them are failing, just the following:

TVSP #6: Dragon of Doom
TVSP #7: The Pursuit of Harimao's Treasure
TVSP #8: The Secret of Twilight Gemini
TVSP #10: Tokyo Crisis
TVSP #14 Episode 0: The First Contact
TVSP #16: Swallowtail Tatoo
TVSP #20: Sweet Lost Night
TVSP #21: The Last Job

I only see in the log:

[Download Check]: download result:  "success"

I tried only "LUPIN THE 3rd TVSP #6" from pluto US ..
.. and can't detect any problem (tested with mp4)

Detecting as a series may lead to a subfolder and the title as the episode title.
However, this has nothing to do with faulty remuxing.

If you encounter a remux problem that I have overlooked
in the log, try changing your mkvmerge video format.
