Usher - Nice and Slow. Watch the vid and tell me what the chords are

Newbie here! Been playing guitar for 15 years now. I'm trying to learn the Usher song "Nice and Slow" Here's a link to a youtube video. This guy is playing this song barred up high. Here's what I think he's playing:

e|------6---------------------6---6-----4----|
B|------6h7---7/9--7/9-7------6---6-----4----|
G|------6----------------8----6---6-----4----|
D|------6h8-------------------6---6-----4----|
A|------6---------------------8---8-----6----|
E|------6---------------------6---6-----4----|

Here is the link to the video. http://www.youtube.com/watch?v=nrLtHoxz19g

I understand if anyone is hesistant to click a link from a newbie. If that's the case, then go to youtube.com and search for exactly the following (not including the quotes): "guamojigga nice and slow"

I'm pretty sure I'm right, but I was wondering if anyone saw something different with the 2nd and 3rd chord. Thanks in advance!
