Weird video glitches that affect my subtitles

[RetroC]

Hello everybody,
I've recently been working on subtitling the cartoon series "Vakáción a Mézga Család" for personal use. The videos of the episodes that I used as basis were in a compilation that I found on the Internet Archive.
They have surprisingly good video quality when compared to other sources on the internet, but at times there are certain 'glitches' on the screen that make the video freeze for a few seconds and then resume.
This wouldn't be a problem if it was something in the recording itself (the videos come from a TV broadcast so that would be plausible), but apparently this is a problem with the video itself as these glitches are slightly different when using VLC, and they weirdly interfere with the timing of the subtitles, even if the timestamps are all correct.
For further information, I am using Aegisub and have completed the first episode. In the program's interface, the subtitles are perfectly synchronized with the characters' lines, but when I load them into VLC, after the glitches happen, they start to change to a more innacurate timing. This is where I took the videos from.

A simple remux can help in many cases.
You can use clever FFmpeg-GUI for this, small, portable without installation.

You should indicate the file and the timings when those glitched happen, we don't have a crystal ball.

Sorry for the late reply...

The file in the Archive.org page is called "The Mézga Family on Vacation S01E01 (hun dub)".

The glitches in question happen at the following timestamps:

03:47
09:06
13:45 (timing starts to get siginficantly off from this point on)
24:18

I tried using cobalt.tools's remux tool, but that one proved to be useless. I have yet to download this program of yours, is it more efficient than the one I tried?

Looks normal for me, this is just that animation is static at those times.

Doesn't this happen to you? (screenshot taken at timestamp 03:47)

My computer was made in South America, does this have anything to do with it? Maybe it's a regional problem.

No, all good for me. Tested software and hardware decoding.
Still you didn't wrote what exact file you have problems with, I've tested only mkv.

Nothing to do with that.

No glitches here. This isn't a computer problem, but a bad download problem.
