Ok, I understand that now. I downloaded a big subtitle file that contains a lot of subtitles. That's what it sees, right? Another question: sometimes I would like two versions of a movie. One subtitled and the other uncensored, for example. But I'm getting errors when scanning new movies and both don't appear. Should I not "overide resolution" to accomplish that?
Subtitles
JavLuv recognizes subtitles when scanning movies. It looks for a subtitle file named the same as the movie, which is typically what you need for those to be played by a media player anyhow. There are a few advanced features in JavLuv for finding subtitles for movies in your collection, but it's sort of a complex procedure, and I've described it in detail elsewhere.
Override Resolution
The "Override resolution" option is for when you want to replace an existing movie with a higher resolution movie. It will show you a dialog and let you know what the old and new resolutions are, and ask you to confirm that you want to replace the old movie with the new one.
Multiple Versions of a Single Movie
If you're not using JavLuv's automatic move.naming feature, it's very easy. JavLuv supports any number of movie files for a given movie entry. Just make sure the movie names are different, and they'll both be listed. You'll want to drop the movie in the correct folder, and on the movie thumbnail, right click and "Rescan Files".
If you ARE using automatic move / rename, you need to play nice with JavLuv so it understands what the multiple movies are:
You can pretend it's a multi-part movie. If you have a movie name and append the parts with -A and -B, JavLuv will preserve both of those.
Another way to do it is to ensure JavLuv categorizes one of the movies as an "extra" movie file. If you look in Settings, you'll see that you can configure JavLuv to recognize some names as "extra" movies, like if you have a movie trailer, or a behind the scenes scene, etc. This is listed under "Movie Exclusions", and by default has a few phrases it looks for, like "exerpt; preview; extra" etc. You can add something like "uncensored" to that list, then make sure you name your uncensored movie that way. JavLuv shouldn't rename "extra" movies.
In either case, the procedure is the same. Manually place the movie in the folder with the current movie, then from the movie thumbnail view, right click and select "Rescan Files".
Note: Yeah, I'm aware it's sort of inconvenient to have to jump to the thumbnail view just so you can rescan files. I should probably add that as a right-click option on the Movie Details page.
