Oh boy, I was afraid someone would ask that! ;-)
As with the last disc, I'm sorry but I simply don't have the time to dismantle, convert and rebuild the project myself (it's even more demanding this time, since there are even more elements involved).
I do see we have a guide on this subject right here: http://originaltrilogy.com/forum/topic.cfm/Doctor-Ms-berGuide-for-Full-PAL-to-NTSC-DVD-Conversion/topic/10111/. I haven't looked into it, but if anyone wants to try it for those in NTSC land they have my full blessing (and I'm very happy to supply menu PSDs or anything else that might be useful).
