Exporting anamorphic (2.39:1) footage to DVD

I'm struggling with exporting my film to DVD -- I shot with anamorphic lenses to the wide screen aspect ratio of 2:39:1. I can view the files okay in FCP after checking the anamorphic box. But once I start exporting with compressor, the only wide screen option I get is 16:9 (1.78:1), which looks squished on screen. the same in DVD Studio Pro, the only option for standard definition is 16:9. How can I make the DVD look "un-squished"? Is there any option for manually setting the aspect ratio? I can't seem to find it... Help please! 😕
