Blu-Ray support in DVD SP 4?

Just been thinking about a new module I am working on which is basically Audio Post Production for TV but aimed at audio type students who have never done any video before. I was just thinking that I should cover Blu-Ray / HD DVD Authoring but it appears that at present, DVD SP 4 on the Mac does not support Blu-Ray. I don't want to use Encore - does anyone know if Blu-Ray is supported by DVD SP 4?
