There exists several DVD-
In Britain, the complete series was released on 14 DVDs. The episodes are in english without subtitles. Before you reach the main menu, you have to endure some trailers to other DVD's. Those could only be skipped by fast forward. The order of the episodes is a little bit different as opposed to the original. But this matters only in episode 2.12 (it's on DVD 10, before episode 3.04). The synopses on the cover says:
"Dandelion's Big Story - It's a rainy day and the baby rabbits gather around for a story session. Dandelion tells them the legendary tale of El-arah and the Black Rabbit of Inlé - two characters who seem strangely familiar..."
But this episode doesn't exist. It was planned, but never produced. And it is no clerical error. It's really "El-arah" in the series instead of "El-ahrairah" (although I prefer the original spelling). The both christmas episodes are cut together to an tv-special and where packed on the last DVD.

In Germany, only one DVD with the first four episodes of the third season has been released. The cover shows badly colored the main characters styled like in the first two seasons. A bonus-episode could be unlocked by solving the game on the DVD.
The DVD is only advisable for hardcore-fans who wants to own everything of Watership Down or wants at least to see a small part of the series in german. All others should buy the british box-set.
