I'm moving you to your own topic.

Convert the vcd audio to ac3, you can use ffmpeggui and convert directly from the vcd dat to ac3 or use other tools.
Then read https://www.videohelp.com/guides/simplistic-guide-for-replacing-dvd-streams-flash-id937#937 how to replace audio streams in a dvd.
BUT you will probably have to manually sync it...
