I've yet to find the Korean DVDs online. Public Trackers/Private Trackers/Usenet... nothing. I'm not on AnimeBytes yet so it might be there.

The Blu-Rays are smeary and poorly upscaled. All home release are scuffed in some way. The Korean DVDs are the best source overall, with a few iffy eps. The French DVDs have the best colors but the framerate is decimated.
