Thanks, for the replies. For final output I rendered the 960×540 movie from a DV 720×480 widescreen comp. Took it into DVDSP and built the 16×9 dvd from that. All and all, throughout the day I built the DVD 4 different ways and got the same, 16×9 results concluding and reassuring that there is more than one way to skin a cat.
Thanks for the help,
