|SPL (Saat Po Long)||R3|
S.P.L. is not currently available in Region 1.
There is a Region 0 version available throughout Asia that features almost exactly the same special features, including English subtitles (it is only missing the 3 trailers for other Madman-released features). It is spread over 2 discs and features an additional Mandarin Dolby Digital 5.1 dub. The video quality has been favourably reviewed by other sites, although I have not personally seen it for comparison.
The Asian Region 0 version appears to be the version of choice, although the two versions are similar enough that most viewers would be more than happy enough with the Region 4 version.
