I'm assuming you have successfully shared the iMovie to iDvd'08 but that when you attempt to burn the iDvd then you encounter and error in burning ..... correct?
If so, check iDvd's Map View button and see what warnings you have and where they are located. Each warning sign will need to be addressed prior to burning to DVD-R Media (Verbatim is recommended here, that and burning a disc image to the desktop to lower the burn speed to 4x or lower)
Hope this helps but if not just come on back.

p 31-32 of Getting Started pdf in iDvd'08 states the following:
Checking Project Files
All the items you added to your project appear in the Media portion of the window
with the path to their locations on your hard disk or elsewhere. If you don’t see the
table below “Media,” click the disclosure triangle to show it.
The Type column indicates whether the item is a picture file, audio file, or a video file. A
checkmark in the Status column indicates the item is present and therefore accessible
to iDVD. If you moved the file from its original location, you can see at a glance that it’s
missing because the checkmark will also be missing. This means that iDVD won’t be
able to access the file. If you notice an item is missing from its original location, you can
do one of the following:
 Locate the item on your hard disk or connected server and return it to its original
location.
 Remove the button that linked to the item.
 Locate the file when prompted the next time you open the project.
Checking Your Project for Errors
If you begin to burn your project without checking it, a dialog appears, indicating if
there are errors in your project. This prevents you from creating a DVD that can’t be
played. However, it’s a good idea to check for errors before you begin to burn a disc.
The most thorough way to make sure your project works properly is to click the
Preview button and use the iDVD remote control to click all the buttons, view all the
menus, and view every video and slideshow. If your project is very large, this could take
some time. You can spot-check your project in less time using map view.
To check for errors:
1 Click the Map button to view your project in map view.
2 Look for warning symbols like the one below (they look like yellow yield signs) that
indicate a problem with a menu or with media you’ve added to you project.
3 Move the pointer over the symbol to see an explanation of the error.
4 Make the necessary correction and return to map view to see if the warning symbol is
gone.
5 To save your work, choose File > Save.
Burning Your Project to DVD
When you’re finished with your iDVD project, you can burn it to a DVD for viewing on a
TV or on a computer equipped with a DVD-reading drive. Burn a disc only when you’re
sure that you’re finished with your project. You can use the following media types to
burn a disc in iDVD:
 DVD-R: Can be used only once
This is the recommended media for iDVD because it’s compatible with most DVD
players and computers. These discs holds about 4.38 GB.
 DVD+R: Can be used only once
These discs hold about 4.38 GB.
 DVD-RW: Can be used more than once
RW stands for “rewritable.” These discs hold about 4.38 GB.
 DVD+RW: Can be used more than once
These discs hold about 4.38 GB. They may not be viewable in all DVD players.
 DVD+R DL (Double Layer): These discs store almost twice as much content as
single-layer discs, but they can’t be viewed in older DVD players.
To burn your DVD:
m Click the Burn button, shown below. When prompted, insert a blank disc into your
computer’s SuperDrive or an external burner.
iDVD burns your disc.
The time it takes to create the disc depends on the amount of video on the disc and
the speed of your computer. Depending on the size and complexity of your project, it
could take a few hours or up to several hours.
