Video Container for 1080p video for SD DVD (using Apple suite)
Just to get this 'answered' for anyone else who might come across this question.

There is no way to get 1080p or 1080i video onto a DVD. DVD's only support SD images (this goes for the disks themselfs, and the players). 

You can however use BluRay to burn HD video, though this would require a BluRay burner and a BluRay player.
