to be honest i would't recommend using Vegas to render an mpeg for dvd. Vegas uses the main concept mpeg encoder and it isn't all that good. it seems to soften the image and its bitrate handling isn't all that great. Your best bet is to render out your finished project to a lossless avi (lagaryth codec works best with vegas) then use Procoder 3 to render the mpeg for the DVD. you can import presets into procoder and i could always give you my settings that i used for ANH:R if you needed them.
