The exact same problem here happened to me as well. One of the videos was even of explicit nature.
Some images were present too
Macbook, file sharing on, shared a folder. Added the share on my apple tv and a lot of videos that are 100% not anywhere on my system were showing. They were unplayable as well.
I had to delete the share and re-add it for it go away. There’s clearly a bug in the apple tv/macbook flow (not necessarily with infuse, could be with macos or tvos)
Can you provide a screen cap of the directory that these files are in?
What version number of Infuse and What version number OS?
How are you connected to this share? SMB, FTP, DLNA, UPnP, etc?
Also, if you open the video’s details page in Infuse the actual filename will be listed near the bottom which may provide a clue as to where these are coming from.
None of the files exist or ever existed on my system(Mac book).
The share had only 2 files, both of which were not the files that were showing.
Any answers to the above questions?
don’t have a screen cap sorry, I reset everything right after.
But I was using TV OS beta 2 18.2
Macos sequoia 15.2 beta 2
connected via SMB
infuse version was the latest at the time. 8.02 or 8.03 (not home so can’t check)
One more thing to look at, do you have embedded metadata turned on?
Is it the metadata that is incorrectly showing a different video but the video itself is correct for the file name?
Embedded metadata was off, metadata fetching was on though
Is it the metadata that is incorrectly showing a different video but the video itself is correct for the file name?
Unplayable video files were appearing. They were videos that didn’t exist(and never existed) or reference anything on my macbook but they had their full metadata appearing (actors, descriptions, thumbnails etc). Some videos had no thumbnails and just titles and some other basic metadata.
There were more files showing in infuse than I even had in the share location
Do you think it’s possible you have a hidden directory, folders, or files on your Mac that you’re not seeing but Infuse is? You can go to the mac and check. To show hidden files and folders on a Mac, open the Finder, navigate to the desired location, and press the keyboard shortcut Command + Shift + . (period). Pressing the same combination again will hide the hidden files.
Stranger things have happened. 
It was a new folder I made that day just for 2 new files. I checked anyway, no hidden files there
Can you provide more info on the files you are seeing in Infuse, and the filenames that are shown at the bottom of the video’s details page?
Do you have favorites added or is Infuse set to scan the entire device?
Can you post a picture of the Infuse > Settings > Library page?
