Encoding from Premiere to Encore high quality

Hi all

Im looking for the highest quality export I can possibly get here, and hitting a few snags. The project (and footage) is HD 25fps, 1440x1080 and I want to get it onto a dvd so it looks as good as possible. To avoid multiple encodings, and therefore quality drop, exporting to encore from premiere pro is what ive been aiming for. Now when I encode to desktop to have a look at my video, ive used the HD 1440x1080 25fps MPEG2 with deinterlacing ontop and it looks brilliant. When I export the project to encore from premiere, my selection is limited to MPEG 2 DVD, and there is a big quality drop in the final product. Seeing as my video is only 8min long, and therefore only a 1gb file when ive encoded to desktop in HD, is there some way I can preserve those HD encoding settings when exporting onto a dvd? 720x576 is the highest resolution I can get out of MPEG 2 dvd, but I know i can get my 1440x1080 footage on there somehow!

Any ideas on how to get that perfect quality export would be much appreciated.

Cheers!
