If your running Vista use Windows DVD Maker. You can take each individual segment from the DVD and place them in chronological order.
I presume you want to put a DVD on several CD's? If so just add up several segments until your around the maximum CD or whatever media format your using. Then publish the project and burn. After thats published put the rest of the files on the second disc.
You can change the overall quality as well to shrink it to fit more on a disc if you want as well. Normally each segment on a DVD is 15mins.
