This is a Chinese import, and to say it is of extremely poor playback quality would be a massive understatement. The playback quality is woeful. In fact, while it is definitely a store bought series, it looks like the episodes may have actually been transferred to DVD from video. It is rather unclear which advertising on the outer sleeve can be believed. It displays the Blu-ray symbol - which these DVDs are clearly not. It lists both Chinese and English subtitles, but I could only find Chinese. I was also unable to locate any of the listed "Bonus Features" at all. With all of this this in mind, I am highly doubtful as to the accuracy of the NTSC and Region All advertising. Before buying this item, please ensure your playback system is multi-regional and capable of displaying all picture formats.
