Unless clearly marked otherwise, adult DVDs are not regionally encoded. This means they are playable on all DVD players worldwide. To achieve this, the DVDs are encoded in NTSC format. With some older television sets, this may cause the picture to be distorted or in black and white. To properly display adult DVDs, your television set must be capable of accepting an NTSC signal (check your television documentation), or, your DVD player must be capable of outputting a PAL signal for your television. Most DVD players have this capability (check your DVD player documentation) and it can usually be set in the options menu of your player. Please note: Recently released Private DVD titles are Region 4 encoded in PAL format. We recommend you ensure that your DVD/TV player is compatible with these systems prior to purchasing DVD titles.
