Just thrown this into my Region A player (a Japanese PS3) and it plays, so it can be assumed to region free, can't confirm Region C tho'!
As with all the other Cine Asia releases I own, NONE of the special features would work. I suspect they are all in std-def PAL. There are three audio tracks on offer; 2.0 and 5.1DTS Cantonese, as well as a 5.1DTS English Dub ,as mentioned above English Subtitles are present too.

Hope this helps
