Burning Blu-ray using Toast on a Mac

[insch]

Does anyone know what frame rate Toast encodes BDs at? I shot an HD film at 25p and I wondered what Toast would do with an uncompressed QT file of it. Ideally I'd like it to encode at 24p or 23.976 fps which would work for European + US markets but there doesn't seem to be any control within Toast. Also what would it do with audio - slow it down by 4%? I also have a 5.1 surround soundtrack but not sure how I would include that within the Toast authoring.

Old question, I know, but I guess no-one has any ideas about how to play BDs on a Mac? I have a La Cie writer but haven't come across any way to play discs yet (other than running Windows on it). Are there any hardware add-ons?

Any help appreciated.

Thanks.
