Dolby Digital with WMA Pro?

[Keith]

This is in the options on the 360...but I have no idea what it is. Is it better than Dolby Digital?

My reciever's instructions manual makes no mention of it whatsoever, but I wanted peace of mind so I thought I'd ask here.

Any idea?

It's just for decoders that can decode WMA Pro. These are pretty uncommon, and it's just MS's way of spreading their format. Few decoders support it, so I'd reckon you should just stick to normal Dolby Digital.
