Exporting for DVD

Hello-

I am trying to export a multicam sequence for DVD.

The basics are these:  A multicam edit in a 1080i/59.94 project.   Obviously I need to get into SD for the DVD.  But there are so many ways, and I've tried a lot of them.  None have worked thus far.

I want to burn in Roxio Toast.  I can get a file in there via a ProRes Mixdown onto a New Sequence, Export < To file < QT Same as Source.  It looks okay except for the interlacing.  It has the combed effect of a wrong setting somewhere along the line.

Thanks in advance for any help you can offer.
