Why do i keep getting this Heap Zone error

Question

I have been trying and trying to export this movie i made in iMovie to iDVD. It is 35 min long and every time i try to export it to iDVD it gets like 3/4 of the way done and then it gives me this heap zone error. The movie is all pictures and are all in JPG format. I have made movies like this before and never got this error. The other movies i have created are 3 to 5 min long and have exported without a problem. I have tried to export it in numerous ways and i get the same error every time. Im running a Macbook Pro with pleanty of hard drive space and 4GB of RAM. I have tried the renaming the movie, restarting the computer, and reseting the RAM. I have disconnected all other devices including the mouse. Nothing but iMovie is running and when i watch activity moniter almost all of the active RAM goes to iMovie until it gets to about 25MB or free RAM and then it fails. I have tried almost everything and from what i've seen on the internet, this is a really big deal and a lot of people are having this problem. Apple needs to fix this.

Hi
To free up hard disk space
• You trash what You don't want any more - and Empty trash-basket (lost for ever)
• You move files and material to an external hard disk
• You move Movie Events and Projects WITHIN The iMovie Program - NOT ON DESKTOP/Finder
( DO NOT MOVE or adjust any folder named iMovie Events or iMovie Projects - if done iMovie loses track of them and they can be destroyed to an un-repairable state)
If You move Events and/or Projects within iMovie to an external hard disk then there is one MUST and one Should
• MUST - it must be Mac OS Extended (HFS) formatted as UNIX/DOS/FAT32/Mac OS Exchange will not work FOR VIDEO (everything else but not this)
• Should be a FireWire one - as USB/USB2 performs badly to me
Trash the pref file
• Delete iMovie pref. file
iMovie pref. file resides.
Mac Hard Disk (start-up HD)/Users/"Your account"/Library/Preferences
and is named. (one or more of these)
com.apple.iMovie.plist
com.apple.iMovie3.plist
com.apple.iMovie7.plist
com.apple.iMovie8.plist
com.apple.iMovie9.plist
com.apple.iMovieApp.plist
and find
com.apple.iApps.plist
While iMovie is NOT RUNNING - move this/these file/s out on to desk-top.
Now restart iMovie.
If You run Mac OS X.7 or more - then the Library in the User-account folder is invisibly and need to be set to be viewable. IT IS NOT in the Library on Root level (when opening MacintoshHD - first window = root level)
( It can be done like this: Open Terminal, then enter: chflags nohidden ~/Library
Press return, then restart, and it will always be visible until the next major update, when you do the same thing again. )
Yours Bengt W - AND A VERY HAPPY NEW 2012 !
