Terrible lip syncing.
Why is it so bad? The old video was like it too, not just the DVD.
"VIVA TRANSSEXUAL, ANIMAL, DIGI-ANIMATION!"
The lip sync is bad because it isn't lip sync mate. This is what we in post-production call ADR...Additional Dialogue Recording. That's what happens when for example the sound didn't come out right during the filming or if they need to change a line and can't or don't want to shoot the scene over again, they just get the actor into the post-production studio to rerecord the lines or record new lines to substitute the old ones.
In some instances it's even a different actor doing the ADR because the original actor's accent or voice is so bad or incomprehensible that they needed someone else to do his lines for him. I have a film in mind as an example of that, but for the life of me I can't remember which!
An example would be Gozer in Ghost Busters. The fashion model playing Gozer had such a thick accent that they had to overdub her lines using a different voice actor.
Often you have to overdub lines when environmental noise (like wind, sea, traffic) obscures the dialogue.
