I remembered reading that the Funimation DVD 
releases for Yu Yu Hakusho will be bilingual 
(although those anime news services have HORRIBLE 
search engines).  The best evidence I could 
provide for you are these pre-order links:

Anime Nation, Buy, Planet Anime, and Right Stuf

Now if you're wondering about the licensing issue 
with those Chinese DVD's, this is as far as I 
understand them.

Hong Kong and Taiwan, according to their laws, DO 
NOT recognize international copyright law.  
Therefore, companies located at these areas can 
steal work from other countries (like Japan) and 
release them under their own brand.  Here's how 
it works:

Anime International, Limited (the Hong Kong DVD 
bootleggers) licenses the right to produce and 
distribute specific anime titles from Hong Kong.  
So they only need to seek permission and licenses 
from Hong Kong, NOT from the true copyright 
holders in Japan.  According to them, these are 
their "official" releases and they will stand by 
that claim.

The same goes from Son May and Ever Anime bootleg 
anime soundtracks from Taiwan.  These companies 
still need to license specific titles for 
copyright, but only in Taiwan (and not Japan).  
This is why even a Japanese music distributor 
like Avex deemed it necessary to open up Avex 
Taiwan in order to protect their properties from 
bootlegging.

I am certain that Japanese companies can bring up 
some legal action against these Chinese 
bootleggers, but it is simply not worth the cost 
and expense PLUS any legal ruling would be very 
difficult to enforce.

Some may think that Japanese companies are 
getting some money by selling licenses to 
bootleggers to produce "Chinese" versions of the 
anime.  But with the bootleg DVD's containing 
Japanese audio tracks, I believe that this is 
either not the case or something else shifty is 
going on.

As far as I know, the ONLY official anime 
releases produced by such Hong Kong companies as 
Anime International are HENTAI.  (It's true.)
