In brief, I find this production virtually unbearable to watch, reflected in the extraordinarily low overall rating below.
First of all, the camera work is quite easily the worst I have yet encountered in opera, jumping back- and forwards between backstage shots of the characters in their dressing rooms (even in the middle of the opera), overhead shots of the pit, close-ups of the sweating Peter Seiffert (whom we also see putting on his final costume during the ouverture before he heads downstairs) and Franz Welser-Mösts wedding ring, shots from the stage aiming at performers waiting backstage etc etc. Furthermore, fans of Jonas Kaufmann, beware: During his only aria we do not see him at all, as the camera only focuses on the faces of Tannhäuser and Elisabeth. Extremely annoying..
This moving back and forth between pre-production and performance shots, takes away a significant part of the potential pleasure of the staging, which I cannot even describe properly due to the odd camera angles. The sets are simple, the stage is bare, but aesthetic it is not. I simply cannot imagine that, visually, this DVD will appeal to anyone.
Musically things are rather better, though not exceptional. Solveig Kringelborn does make a rather fine Elisabeth (though I personally find her irritating), not entirely matched by Isabelle Kabatu as Venus. Fine performance from Roman Trekel (slightly neurotic) and Peter Seiffert (equally boring). Franz Welser-Möst is more than competent though not overly imaginative.
The bottom line (scale of 1-5, 3=average):
Peter Seiffert: 3
Solveig Kringelborn: 3
Roman Trekel: 3
Isabelle Kabatu: 2
Franz Welser-Möst: 4
Jens-Daniel Herzog: 2
Overall impression: 1
