Also, the discs are single-layer and not dual layer.just sayin'! Although that has nothing to do with copyright protection really.
Copyright Protection: Unlike the American DVDs, there isn't any on these! Just thought I'd note this.Region Coding: Although the back of the packet states it's region 3 (and I've been reffering to it as region 3), it seems that it will work for all regions, so you don't need a DVD that can do multiple regions (multiregion), although you'll need a display that can handle PAL signals.No subtitles/closed captions are enabled by default so you'll have to enable them some way or another. They don't include what sound effects happen from what I can see though.
The English ones seem pretty accurate, obviously I'm not sure of the Thai ones, but I'm guessing they're alright.
