I know I'm necro-posting, but I just stumbled across this DVD myself last night and have been looking for info on it. For anyone interested, you can find a copy (either MP4 or ISO image) of the DVD on archive.org:

Documented on VGMDB here:

I'm trying to find a translated chapter listing, but not having much luck with that.
