It looks to be a recording of Moya's gig at the Avo Sessions in Basel - the date they quote is definitely right for it.
It was definitely recorded, and went out on Swiss TV. Unfortunately, my German isn't good enough to be able to work out whether the TV company released it as a DVD commercially.
I have to admit that a couple of things on that web page rings alarm bells. First off, I'm surprised they seem to have used the cover from Two Horizons on the disc. As far as I know, the Avo gig had nothing to do with a Two Horizons tour, it just happened to be about that time, and Moya used the opportunity to advertise!
The other thing that would concern me is that it mentions a DVD-R. Most commercial DVDs only have a region code, so a bit of me wonders what the mention of a recordable DVD is for? :S
Sorry if this seems negative, but I really don't want you to get caught out. They have a facility on the site to send them a message, so I'd get in touch with them to find out more, before you part with your hard earned cash!
Good luck!
