Truly, I meant to title this 1920 x 1080.
while looking at another discussion, I see I wasted my money on this approach.
The max is 720 x 480, "end of story."
Thanks, I guess.
You need clients who have HD tvs and Bluray players...
Yes, DVD-Video will be 720 x 480 for NTSC. That is it.
Now, if played through an up-rezzing DVD, or BD player, the player's chip will likely give you better results into an HD TV, than one would get with the 720 x 480 on a non up-rezzing DVD player, into a CRT TV. Still, it will not be as good as 1920 x 1080 to BD. DVD-Video is just limited.
Good luck, when your clients do go to BD, and you can produce for that, things will get MUCH better, as Stanley points out.
