Multiplexer error - There was an error during formatting
I'm using a brand new iMac 3.06Ghz and iDVD '08. The system software is completely fresh will all relevant updates applied. When burning to physical DVD's or to disk images, I'm frequently getting the following error message:

This error message occurs right at the end of the burn process and is occurring with about 80% of the burns I'm doing. Sometimes if I format a disk and try again it works second time round.
I went to an Apple store yesterday and spoke to a genius about this problem. I was told that instead of burning directly to a DVD, I should do the process in two stages. Firstly, get iDVD to make a disk image on my desktop and then use Disk Utility to physically burn the disk image to a blank DVD. Well, I've tried this as well and I'm no further forward. The same error message is being displayed. I've run through this guide: http://support.apple.com/kb/HT1583?viewlocale=enUS&locale=enGB
and in answer to the questions:
1) Software update run, no updates available
2) I have over 820GB of free space
3) There are no non-Apple QuickTime plugins installed
4) No third-party iDVD theme's used
5) I'm able to burn from other applications like Finder and iPhoto
6) Have run hardware test. No problems identified
7) Issue occurs in the final few minutes of burn, no thumbnail shown
8) ?
9) Have tried re-encoding project
10) Intermittent fault - happens on other projects at random
I've done some googling and can't turn up any other information. Also searched these forums but quite a bit of what I've found relates to Final Cut. What else can I try?
