I've sent an email to a friend who's been working on the dvd's packaging. I think he might know individual chapter lengths too.

Cuts and Additions:
Prologue flashbacks truncated and re-ordered to make
dwarves more sympathetic, and moved to where Bilbo learns the story during the
unexpected party. A few establishing shots are altered to fit the scenes into
context.

Frodo cut

Dwalin/Balin head bump cut

Some extra
shots of dwarves being messy cut

Redundant Thorin & Gandalf dialogue
cut

Gandalf's exposition on Bilbo's thoroughly unremarkable childhood
cut

Thorin & Balin's conversation after "it appears we have lost our
burglar" cut (shot of Thorin reversed so that he is look toward Bilbo instead of
away)

Misty Mountains song uses footage excised from the flashbacks,
converted to slow motion, to create a montage.

Entire Pale Orc
plotline cut--this involved many cuts throughout the movie, starting with the
flashback after Fili and Kili tease Bilbo

The dwarves no longer have a
silly fight scene with the trolls only to throw down their weapons for a
companion they don't even like. Instead, they charge the trolls, and we cut
directly to their cooking over the fire. Clearly the charge was a well-laid
plan. (Finagling the audio for this cut was the biggest pain in the rear for
the edit; I doubled and reversed the battle cry to avoid sounds and music on the
center track.)

Troll banter on seeing Gandalf cut

Radagast stays!
He sets up the Necromancer plot for the next movie. However, his appearance to
Gandalf happens after Rivendell rather than before, and Gandalf is implied to
separate from the dwarves with him. A shot back to the sword helps explain what
Gandalf has just received.

The entire warg chase scene is
cut.

Thorin's concern that the elves will stop them cut (but mistrust
kept)

Elrond's skepticism concerning the Erebor quest cut

White
Council removed entirely. Ugh.

Stone Giants cut. Blerg.

Fall
down goblin hole made less ridiculous

Goblin King trimmed

Every
single frame of Gollum kept!

Goblin chase scene cut from five minutes to
one. This involved many small cuts.

Many small cuts reduce the Pale Orc
from a nemesis of Thorin's to the Really Angry Orc who pursues them after they
killed the goblin king. The dwarves and Bilbo do not leave the tree once chased
up. The Eagle rescue has also been trimmed; they do not fight the wargs except
to drop a tree on several. Our only explanation for Thorin's KO is that falling
from trees and eagles can be rough on a dwarf; this is the only significant
continuity issue for which I could not find a fix.

Bilbo becoming
accepted as a DwarfBro cut

Erebor mattes replaced to suggest a greater
distance from the mountain--thanks to TM2YC for creating the modified matte I
used for this

Ending credits music modified...
