How to Rip poorly authored/maintained VCD (mplayer)

[AmarD]

Hi all.
There is a very important VCD I'd like to copy.
I've used, VCD imager which does not detect the disc as VCD at all.
VLC which gives Pulse audio error.
But mplayer which dumps the stream really well, but only upto 42%(19 minutes), giving input/output error. I know, it's scratched as hell, so i tried playing from 21 minutes onwards and it plays really well upto the end. Even an old DVD player also skips those difficult parts.
This is the command I used to play from the right time

mplayer  /dev/sr0 vcd://2 -ss 21:00:

But when i use -dumpstream, it starts extracting right from the begining, which is not what I need.
I tried to approach mplayer forums, but i don't know wether they are still working or not.
Thank's in advance.

Well, you could dump to lossless images and audio instead (-vo png:outdir=/path/to/somewhere:z=9 -ao pcm), but that takes more space.

Thank you.
I actually used cdrdao to rip the VCD to .bin .cue and then was able to extract the MPEGAV01 file on a windows PC.
Later transcoded to mp4 using ffmeg.
I'll use your procedure if cdrdao fails in the future.
Thanks!
