found this in the archive:

I would like to save more than 90 minutes to a DVD using iDVD3 but 90
minutes seems to be the limit.  If I could save the iMovie as a disc
image I could use DVD2oneX to compress the movie down to 4.4 gb.  But
there doesn't seem to be a way.  On the jewel box for the blank dvd it
says the capacity is 120 minutes at high density and a lot more and the
lower qualities, but how do you do it?

Here's a link to a web page that describes a fairly complicated way to do
it:

Below I've included a copy of a post from Erica Sadun. It describes a method
for lowering the bit rate used to encode a project in iDVD. If you try it,
let us know how it worked!  :-)

So, out of curiousity, I decided to take a break from
writing and see if I could make iDVD encode at the
bitrate I desired.

I edited the ProjectData file from the project (without
iDVD running)

  <key>Bit Rate</key>
    <dict>
     <key>Is modifiable</key>
     <string>1</string>
     <key>Max value</key>
     <string>9800000</string>
     <key>Min value</key>
     <string>2000000</string>
     <key>Order</key>
     <string>20</string>
     <key>Property name</key>
     <string>Bit Rate</string>
     <key>Property persistent name</key>
     <string>Bit Rate</string>
     <key>Property type</key>
     <string>3</string>
     <key>Value</key>
     <string>2000000</string>
    </dict>

I enabled background encoding, adding a short movie and
sure enough, (after extracting the file from the project
file MPEG folder):

/Users/ericasadun/Desktop/MPEGS/try1.m2v
   Mpeg 2 Video File
   Estimated Duration: 06.15s
   Aspect ratio 4/3 (TV)
   Interlaced, chroma format: 4:2:0
   Video Format: NTSC
   Size [720 x 480]     29.97 fps    2.00 Mbps


I got the 2.0 Mbps that I requested.
