guachi,
Thank you for your stack trace, but miserably, I don't think that it's related to the video generator.
Today, I created a 100 MB video at max resolution under Mac OS X then under Windows XP with 512 MB of memory (it's a "virtual" PC under Parallels Desktop). It took much more than 4 hours and there was no problem.
Maybe some images of your video can't be rendered because of this bug.
Does it fail also with other home files?
