    Are those 366 MB files highly compressed videos, .avi or .mp4 (Divx/Xvid or H264) for example?
    How long in minutes are those videos?

    Have a look at Activity Monitor ( Applications / Utilities / ) and select All Processes and sort by CPU to see how much CPU iDVD uses.

    To edit your thread title, just click on the [​IMG] button on the bottom right of your original post and then click the "Go Advanced" button below your message.

    Have you also taken a look at MRoogle, since that question may have been asked several times?


    Example: iDVD takes 5 hours to make a DVD with 3x YY min of video on an i7 iMac

    How long are those videos? Each is 42 to 45 minutes I suppose? Any you want to burn it to a Single Layer (SL) DVD (4.7GB, 4.37GiB), thus 126 to 135 minutes of video are crammed into 4.7GB? If that is so, then iDVD needs to work very hard, as the MPEG-2 codec is not as efficient as the MPEG-4 codec variants (like Xvid or Divx or H264), thus it normally takes up more space (150 minutes on 8.5GB/7.9GiB).
    Have you also taken a look at Activity Monitor or "How to maximise your MacRumors troubleshooting experience"

    What does Activity Monitor say (three times the charm?) during the encoding process?

    And again, 135 minutes of a SL DVD is too much, unless you want low quality, something Professional Quality seems to be the opposite of.
    Either use Dual Layer (DL) DVDs (8.5GB/7.9GiB) or only take two videos for an SL DVD or choose a lower quality setting.

    And have that look at Activity Monitor during one of those encoding processes to see if it takes advantage of all the four cores.
