Can't publish-project too long

Question

I will give more background later, but to put my issue shortly, I will give the following info:
I have one video clip that I have trimmed (by taking a bit from the beginning and a bit from the end).  It is almost 2 hours long (1:56 to be exact).
So, I have one clip in the project and no music.  A pretty simple project.  I say share with iDVD.  It says it will take about 2 hours or so... and it seems to be going through all the appropriate processing, then, as it approaches the end of the process, it pops up with an error message from iMovie:
Unable to prepare project for publishing.
The project could not be prepared for publishing because an error occurred. (Project is too long.)
(I'd give the little illustration, but whenever I bring up "Grab", it hides the pop-up error.  Once I click on iMovie, the pop-up error returns.  Weird!-- But this is a moot point as this isn't the problem- I need to publish my project to iDVD.)
Other facts:
I have 11.4 GB available on my hard drive, so this is not the issue.  (I had cleared up space thinking that was the problem as this is the second or third time I've attempted)
The original movie file that is in the project is about 2.29 GB in size.
Oddly, it seems that an error pops up under my Aperture saying I don't have sufficient space for the library volume.  I was doing nothing on the MacBook while this project was publishing, so not sure why that is coming up... and not sure why it would say there isn't sufficient space for the library if I have tons of space on my hard drive.  And, why is it popping up each time I try to publish my iMovie project?  There aren't any photos from Aperture even in the project.
This mp4 file that I am using is actually a file produced by Elgato Video Capture (This is a VHS to digital transfer), if this matters at all.
Previously, I had imported some jpegs into iPhoto, (for another iMovie project that I needed photos for), but iMovie could not "see" them even though they were there plain as day.  So, I imported into Aperture those same photos, and iMovie was able to "see" those in Aperture (these 11 photos are all I have in Aperture as I have not ventured into Aperture much yet-- but needed a work around for some reason on this OTHER project).  I give this info in the instance that this Aperture to iMovie link could be causing any issue with this project despite no photos being included in this project.

Even though it might seem like a lot of space those 11.4GB of space, you still might need a little more especially as iDVD can only just about handle 2hr. worth of video material to fit on one DVD-R. The target free space you might want to get closer to is something like 25GB of open free space (almost double what you have free now). Partially the reason is all that 2 hours needs to be converted from the format it's in now Apple Intermediate Codec (AIC) to full MPEG-2. That's where things really start to expand and inflate. Then iDVD takes that whole MPEG-2 encoded file and makes an equally large Disk Image out of it that can then be burned to DVD-R. So the space requirements balloon up very quickly.
Sharing directly to iDVD can be full of surprises. Instead what you might want to try rather than Sharing to DVD is instead sharing it to the Media Browser from iMovie first (Large Size). Quit iMovie wants it completes the encoding. Open iDVD, go to the Media button down in the lower right hand corner of the Window and at the top of the Media Browser choose Movies. In the window you should see an iMovie Star icon with the project you shared immediately beneath that. Create a new project and drag that shared iMovie into the project window.
