xradman, with my copy the sound (both on the pcm and the DD5.1 track) was not seperated over the different channels (so sound from the speakers is all the same, even dialogue); very disturbing; do I have a bad copy ?

LoveHK Film Review

This was a fun film. Unfortunately the PQ on this is probably one of the worst I've seen, even from a Taiwan distributor. PQ is on par with what you used to get with non-anamorphic SL DVD-5 from HK. Audio and subtitles are pretty good.

Video: 1080p24 AVC encoded 2.35:1 (on par with VCD or non-anamorphic DVD)
Audio: Cantonese PCM 5.1 or DD 5.1
Subtitles: Optional traditional or simplified Chinese, English
Extras: Trailer for Bangkok Dangerous

sound is unfortunately unwrapped: very strange for a Blu Ray
