Windows Spanned Volume

I have two 1TB drives that are used as a spanned volume in Windows Vista Ultimate. This basically allows the two physical drives to function as one without any redundancy. I keep all of my movies on those drives for access throughout my house.

Leopard can see these drives in the disk utility but it obviously does not automatically recognize them in this manner and mount them appropriately. Is there any way to access these drives within OS X and not destroy the data that is on there? I've seen the concatenate option, but I'm not sure from this point...
