I didn't even know this was out until i heard news about the dvd's release date.  Slayer playing live on their "Divine Intervention" tour is perfect since i love that album.  I watched all of the concert footage on youtube and it is excellent!  I haven't watched the behind the scenes stuff yet but the concert footage alone is worth it.  The dvd comes out in a month or two and its only $10 on amazon.  Support your Slayer!
