Don't export HD content to avi and then to dvd. Bad idea, this will cost you quality. HD is not DV. Export directly to mpeg2-dvd either in Premiere or Encore. If you want to use Encore for encoding use Dynamic Link and use default settings but make sure the field order is upper. Dont crop off the black bars on the side due to the way it is scaled down. Just leave it, you'll get used to it. Have fun.
