I am not 100% sure with iDVD5 but thew point is:
in the past you would encode your disc and burn it.
It would offer to burn another disc.
If you refused the offer and quit the program, burning another one later
required a full re-encoding and I, anyway, found this inconvenient.
If you just make a disc image directly from iDVD then you can trash 
your project and related DV files and so forth
and burn a disc at will from the image.
This has worked fine for me w/ Toast, and i suspect would work with 
discburner too.
Even though Chris has problems Alex has pointed out that unlike CD's 
DVD's are infact data discs.
  Probably Chris' problems with the Image were due to screwing up the 
file hierarchy, which is important. The easiest way to see what the 
hierarchy is is to insert a commercail DVD, then make sure that yours 
is similar in basic structure.
Which is to say that the TS folders should be inside another folder. 
That is your DVD.
