seek from command line doesn't work correctly

os : windows 10
vlc : 3.0.11

I wanted to extract from a DVD with --start-time and --end-time. I had previously watched the DVD and noted down the times from the displayed timestamps.
###
problem : they don't match, the further the DVD plays the more the times differ, as if the playing extracting would use different timescales
###
example : at a certain songstart VLC showed 29:55 when watching the DVD, in the extracted audio this was occurred at about 30:10 ( that diference might be due to mp3 vbr of the audio file ), but when I want to get that with --start-time I have to set that to 28:20. It would seem that the player gets it right but the seek from the command line with --start-time doesn't position correctly.
###
anybody knows what this is about and what to do ?

Well, what I eventually did was to create a complete extract and use ffmpeg to cut it into parts using the times observed while watching the DVD. Worked well.
###
What does this tell us ? It seems you can't use --start-time and --stop-time .
###
That would be a strange bug - or is it a feature ? Did I miss something ? Feedback would be appreciated.
