Excellent A/V quality, very nice packaging and menu. A shame that we didn't get all of the extras, but what can I say... that's Toei for you.
The subtitles are a little bit off, though. When Shin bests Ken early on in the film he says "Nanto Gokusatsu Ken": He's literally saying the name of his attack, something Manga translated as (I believe) Hell's Death Fist of the South Star, ages ago. Discotek has something like 'Nanto can't be harmed', which really isn't even close. It's also weird that they have Jagi calling Raoh "master" when he's using the word for 'brother'. That one's just... I, don't even know what's up with that.
Don't get me wrong, awkward subtitles are better than no subtitles, or even dubtitles, and the old Image DVD was dub-only at that. This is by far the best English friendly DVD release the film has ever had, and evidently Chris (and at least one other online reviewer) didn't notice anything was horribly off. Odds are people who aren't already familiar with the film won't notice anything awry, but it's still worth mentioning.
