Change DVD Track Order?

I brought this DVD recording of a concert, but some of the tracks are out of order. It goes

The Root of All Evil
The Answer Lies Within
These Walls
-Cut-
Sacrificed Sons
Octavarium
-Cut-
I Walk Beside You
Panic Attack
Never Enough

When it SHOULD go

The Root of All Evil
The Answer Lies Within
These Walls
I Walk Beside You
Panic Attack
Never Enough
Sacrificed Sons
Octavarium

So my question is..
Is there an easy way to extract those two tracks and move them to the end of the recording so I can re-author a properly ordered disc?
Thanks!
