Censored or time compressed so they cut some scenes?
CX audio instead of Dolby Stereo also seems odd.
This appears to be its own release. The Hong Kong release is uncut with Cantonese subtitles and is the same master as the US VHS Pan and Scan.
It’s also an officially licensed release. Not a bootleg. Very strange indeed, but this was for the South Korean consumer or rental market I assume.
