1. After downloading the subtitle file, unzip it and put it in the same directory as your avi file; Change the name of the subtitle file to the same as that of the avi file (only with a different suffix) (note that the suffix of the subtitle file is. Srt), and you can see the subtitles by opening avi with a video storm.

2. Subsuffix?

There should be an idx file, right?

Hehe, subtitles in sub format generally have two files in the same movie, namely suffix idx and suffix sub. ...

I've never been in such a situation. I wonder if what I just said will help you.

Ps: I wonder if you are looking for the subtitles of Sleepless in Seattle. I tried the subtitles downloaded from the link you gave me, and you can see that it includes Chinese and English.

I use kmplayer and mpc, and I haven't made any settings, hehe.
