No. iDVD does not have that feature. However, there are two ways you can do this:
1 - join the 10 segments into one movie file. It's quite easy if you have Quicktime Pro and Quicktime Player 7. Other video editing apps can do the job.
2 - you can create a slideshow in iDVD and add each of the movies to it so they all will play one after another:
Set the Slide duration to anything but Manual. Do not select a transition and add no music to the slideshow.
Remember, the playing time of the entire project should be less than 120 minutes including menu's playing time in order for you to use a single layer DVD disc.
Follow this workflow to help assure the best qualty video DVD:
Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image menu option. This will separate the encoding process from the burn process.
To check the encoding mount the disk image, launch DVD Player and play it. If it plays OK with DVD Player the encoding is good.
Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality. Always use top quality media: Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.
