Exporting a 1hr HD video small enough for a DVD

Hi

I'm new to this and would really appreciate some help. I'm trying to export a 1 hour long recording of a play so that I can burn it to DVDs for the cast. I will be using iDVD for the burning and that seems fairly fussy about what formats it will take. I want to export the film small enough that it will fit on the disks but right now when I use the standard quicktime movie settings it comes out as a 36GB file. Any help would be greatly appreciated.

iDVD should compress it down just fine. What codec is it now, what frame size, what frame rate, what camera did you shoot it with?
