Thanks Steve and ZikZak. I've dumped the DVD with mencoder onto the HDD but the chapters are still lost. I thought the chapter marks are stored in Stream #0:0 below but they are not as VLC nor ffprobe don't show them... I wanted to process the vob-file with ffmpeg afterwards ;) FYI: I didn't encode anything in this dumping-step in order not to loose quality.

Anybody knows? @ZikZak: How do you preserve the chapter marks with mencoder dumping a DVD? I'd preferably use an commandline-tool but as it seems the next step for me would be to try makeMKV - the newest Linux Version I found ist from year 2009 - is this correct?
