HDV Quicktime Movie for 26'x11' Silver Screen
 

I'm building a trailer in FCP that I'm outputting using Quicktime conversion with a 2553 x 1080 aspect ratio (26'x11' movie screen). The file it creates is the correct ratio, but is that Quicktime Movie HDV? If so, can I burn that file alone to HD DVD?

I know that when I output it to an HD DVD though DVD Studio Pro it is HDV *but* it loses the 2553 x 1080 ratio and becomes 16x9.

If I can't burn HDV at 2553 x 1080, is it possible to hook a Mac up to the projector and play the Quicktime Movie in HDV at 2553 x 1080? If not, do I need to have it produced somewhere?
