I don't have any answers for you (I'm considering getting one actually) but could you tell me if the optical out can passthru 5.1/DTS from a macbook?
I must admit I don't know off-hand, but after a google, it looks like it's been flaky on previous AE models:

Seems like they don't test it when they release new firmware :S
