Hasta La Motion!

I was watching a scratch demo at assimilate’s website. HE was working with 4k plates that were in an HD 1920 project. So he resized the image "down" to fit in the 1920 window. I said to myself, wow that must be nice to compact all of those 4k pixels into a 2k project. ( almost 2k)

Should I be doing the same with HDV 1440 X 1080 if my goal is to render to DVD?
For example, I set up my project to 1440 X 1080 and then render out to DVD standard. I’m guessing that the transcoding dumbs down the resolution to 720 X480.
So my question is which is the better deal? Working in a 720X 480 project and Resize "down" to fit 720 x 480 (which should compact those nice 2k pixels into 720)

Or

Work in 1440 and let the transcode do the work for me?

Thanks,
