Video 4 - Not the worst that I've seen, but not the best. The video looked like it was ripped from a better quality file (something must have happened to decrease the quality). Audio 4 - Once again, like it was ripped from a better quality file. The audio is not terrible, and should not be a problem even at high volumes. Subtitles 3.5 - HK originals. You can get the basic point from them, and every now and then will get a sentence that is decently grammatically correct, but they are not that clear. The subtitles themselves are legable, so you can read them easily, but every now and then there will be missing subtitles. Overall - Not that bad a set. Worth seeing if you're a fan of Dunbine, but you have to keep in mind that the subs are not that great so you're missing some of the plot.
