Nope- do not remove a field that's halving your resolution. Lemme guess- you went directly from 1080i to MPEG-2? That's not the best way to do it, because downconversion and encoding at the same time=low quality. Instead- output a standard definition 16:9 version of your 1080i timeline first to ProRes. Then use that as an MPEG-2 source for your DVD. Guarantee it will come out great...
