The LG Goldstar GDI 750 was sold in Korea, I've never seen a player with the korean signs on it. It had an integrated DVC and it was bundled with a special korean CD-i disc by LG about the Mulk and Swank's Music Show.
The Mulk & Swank Music Show was produced in 1996 by Tooniverse. It requires the Digital Video Cartridge. It is also the first korean CD-i disc aimed at kids that I come across!
