I don't know much about SADC/DVD-Audio/DualDisc formats, but if your computer hardware (CD/DVD player) can't handle them, then there is no way your software will.

I would think the main question here is whether FreeDB and CDDB support these hi-res formats. Unless they do, there is little use in adding them to programs like OrangeCD.
