I finally got my Hi no Tori DVD today and so I'll make a small review just for the fun of it.
The package is quite nice (as you can see in the pictures).
As for the picture quality of the anime itself, it's good as well. Not as good as maybe Disney DVD's but far from bad. The sound is in DD 5.1 (both German and Japanese) and...I can't judge how good it really sounds since I only have my old speakers who aren't made for something that advanced XD.
The German dubbing is...well...sadly not that good. I would even say it's pretty bad but at least there is one so I can watch it with my parents once.
The subtitles are well made and as far as my Japanese goes I would say it's well translated. It's also good to read.
All in all I would say it's a pretty good DVD and I'm very happy with it. ^^ I'm looking foreward to the others.
