I can not find a release in Region 1 of Butterfly Lovers. The region free Hong Kong Release is NTSC, not 16x9 enhanced, includes Cantonese and Mandarin Dolby Digital 2.0 audio options but no extras. The Region 2 French release is 16x9 enhanced, has Cantonese Dolby Digital 2.0 audio, trailers and a 60 page booklet. There are burnt in French subtitles, but no English subtitles are available. Accordingly, for English speakers Region 4 is the best option at present.
