Distorted images on VOB subtitle import

[fiammybe]

I am using version 4.0.5 on Windows 11. I import subtitles from DVD's in order to turn them into SRTs.

I use the function File > Import > Subtitle from VOB/IFO (DVD). I tried it on 4 different DVDs (old ones, recent ones) and at irregular intervals, there are frames with issues in the ripped subtitle view:

• the image ripped for the subtitle has noise, making it impossible to read the subtitle
• there is some noise, and the subtitles appear in the upper half and the lower half, but smaller

Both of these make it impossible for the OCR systems to recognise the subtitle correctly. These are PAL DVDs, 25fps, and no configuration changes to the standard install of Subtitle Edit were made.

If you have other .ifo files, then try them...

Just to establish some sort of baseline, does it happen for you with this one?

@darnn the issue isn't there on your files. I also verified that the issue is still there when I first copy the DVD content to my local hard drive, and then launch the subtitle rip. It is still there.

Sorry, I cannot re-produce this... we will need a sample file in order to look at this.

I understand, I will upload a sample in a few hours.

Huh. Yeah, that does certainly happen on my end as well. And it must be the way SE is parsing it, since extracting the idx/sub files with VSRip produces something that opens fine in SE.

Using VSRip is a temporary workaround, thank you very much for the suggestion.
