DVD Rebuilder has no PAL to NTSC settings (and it really really should). In fact AFAIK there is no single program that can do such a full conversion (though movie-only options abound). If you are interested in rolling up your sleeves, take a look at my hefty Full PAL2NTSC guide over in the How-To/Technical section of this forum.

That's a bit off topic.

On topic is a question that I'm sure has been asked and answered but I'm just drawing a blank on... are the effects in this cut theatrical or the Director's Cut redone effects?

I personally had no problem with the new ones and wish they went that far when they remastered TOS. Though with HDTV used as a source in this, I'm guessing there are no updated effects.
