I saw the longer cut at the American Film Market back in 2006. Two sequences I know were cut... the first takes place right after Ethan and Sarah flee from the therapist's house and steal a pizza delivery car. Jack flies in and holds Buraki at bay with energy blasts from his hands so that Ethan and Sarah can escape.
The second cut scene was longer. The FBI calls in a bunch of bounty hunters and animal trappers and tries to hire them to capture Buraki. When the agent explains it's a giant monster with diamond hard scales all the hunters run away.
Based on the preview screenings, Younggu Art edited the film before it was released to theaters in Korea and the US. I don't know if the deleted scenes are included as extras on the Korean DVD.
