@justin per the request of @kcador I am going to quote what I wrote here: 📚 The Library on Trakt: What It Is and Where It’s Going - #25 by CajunRob
One thing that I’ve noticed as I am going through my list of collected items in my library is that Trakt appears to be classifying digital items as BluRay after syncing from Plex. I’m not sure whether this is because it’s picking up the source from the filenames used or what. But surely anything synced from Plex should automatically be considered digital, no? Even if it isn’t necessarily playable because of App permissions. It also seems to me that much of the reliance of being “playable” from some site is based on Justwatch finding where (if anywhere) something is currently able to be streamed. That negates anything we might have purchased digitally or own through a service already.
ETA. After downloading the CSV files for my Library, I can now definitely see that anything imported from Plex that had the source of the file set as a BluRay in the filename (e.g. move.title.year.BluRay.resolution.audio codec.video codec) is currently being tagged as Media type=1 in the watch list instead of media type=0). Unfortunately from what I can see there’s no way of uploading an edited version of the Library to accurately fix the items to be correctly displayed. Am I honestly expected to manually one by one edit >1000 items?
While it is incredibly helpful to see it listed on Trakt that the original source of a digital file was a BluRay, DVD, or Web, it clearly is going to play havoc with the new Library in the future if Trakt assumes that because something was encoded or remuxed from a physical copy that it isn’t a digital file. Every file I have tagged through naming something with the words BluRay in the title are for some obscure reason being tagged as BluRay (media type=1) in my Library. That simply makes no sense seeing as (a) Plex can’t handle physical media, not even from a folder base or .iso file, or even ifo/vob, and (b) as it was synced through Plex Sync it clearly is digital.
To my knowledge there’s no tagging at all being done by Plex ever. So does this mean that Trakt is scraping and processing file names?
