Thank you so much for your reply!
The media folder was just in my Documents, but I was able to find the Anki2 folder and moved the media and TSV there. The screenshot below shows the media folder (audio and snapshots) are currently in the Anki2 folder.
After doing that, I deleted my original, broken Subs2SRS deck and made it again with the TSV that is now in the Anki2 folder. The cards all look exactly the same as before. (All screenshots in this reply are from after I did this.)
Here are some additional screenshots showing the media file names and where they are located.
Snapshot: (the snapshot file name comes from your suggestion of looking at the HTML)
The audio file name (“Goblin_Ep_1_1_0.14.01.630-0.14.03.310.mp3”) is the same as in the previous screenshot of the Anki note/card.
ALSO: I re-made the deck once when the media was just in the Anki2 folder, and once when the media was in the “User 1” folder in the Anki2 folder. My Anki account I use is currently labeled User 1. The resulting deck was the same both times.
Thank you for your suggestions again; I seem to be back at square one, though. I’d appreciate it if you have any other ideas.
