Problem with psychedelic colours after encoding in iDVD6

Question

I'm working on a long project in iDVD6 that just fits on a dual-layer disc. Everything is ok except for one particular movie. This clip starts out in mostly a greyscale colour scheme then dissolves to full colour after a few minutes. In the project, this plays fine.
I encode to a disc image and no errors are reported. On a dual g5, this takes about 10 hours to encode.
When I mount the image and check it, this colour problem arises. After the grey sequence, the colour sequence looks like random colour garbage. Very psychedelic but not the look I need for this project.
I tried deleting the encoded assets, re-exporting the movie file in question a couple times, and also sneaking some colour information into the greyscale opening sequence via a single line of colour pixels across the top of the 640x480 frame.
I will try exporting the movie from my editor with another codec. Any other suggestions for fixing my LSD video problem?
Thanks,
Jaeson

Hi
Was just a shoot in the dark. I try to have > 25Gb free. So You are well up to it.
No clever ideas - sorry.
Not knowing the origin to Your problem - General approach when in trouble is as follows:
Many possible origins. Most common:
• Free space on internal (start-up) hard disk if it is less than 10Gb should rather have 25Gb
• Hard disk is untidy: Repair Permissions, Repair Hard disk (Apple Disc Util tool)
• Delete iMovie pref file - or rather start a new user/account - log into this and re-try
• Third party plug-ins that doesn't work OK
• Program miss-match: iMovie 6.0.3 or 6.0.4, Mac OS X.4.11 AND QuickTime 7.4 - is OK
iMovie pref file resides: Mac Hard Disk (start-up HD)/Users/"Your account"/Library/Preferences
and is named: com.apple.iMovie.plist
While iMovie is NOT RUNNING - move this file out to desk-top.
Now restart iMovie.
