Ripped from DVDtalk.com reviews for LABYRINTH:SuperBit
Video: Labyrinth is presented in 2.35:1 anamorphic widescreen. Considering this movie was made back in 1984, this movie looks pretty darn good. We still have the usual streaks, spots, and black marks on the final print, but aside from that, the picture is clean and sharp. There is a touch of graininess present, but it's not as bad as The Dark Crystal - Superbit. The increased bit rate did wonders for this movie, as it looks significantly better than the original release. Again, people with small TV's will probably have a harder time noticing a dramatic difference, but even they should be able to make out that the overall product looks nicer.
Audio: Like all Superbit titles, we get a Dolby Digital 5.1 and DTS audio track. Both tracks sound nearly identical to each other, but you may have better luck with the Dolby Digital track syncing up with the actors. I found that the DTS track almost every time was out of sync with the actors. It's possible that my DVD player might be having problems with the flagging of this audio track, so I mention this just as something to look out for. I had no problems with audio syncing with the Dolby track.
For the most part, the audio quality is very similar to that of The Dark Crystal - Superbit. Deep bass is almost non-existent, and there is a slight fuzzy distortion sound present in all of the speakers. However, the upper sound range seemed to be crisper than that of The Dark Crystal - Superbit.
In terms of the original Labyrinth release, these audio tracks sound much better. The original gave only a Dolby Digital 2.0 track, so already we're receiving more separation then what we've had before. The original track sounded harsh, and deeply compressed, whereas the new 5.1 and DTS tracks have more room to breath with the increased bandwidth. This Superbit version definitely sounds better than the original, although it would have been almost impossible to sound worse.
