Hi all.
I am trying to confirm compatibility of B&N's DRM on ePub with Sony.
I was able to confirm that a book purchased from B&N does not work in the Sony reader software (it ignores the file). This is not surprising though since B&N's DRM is new and has yet to be merged back into the Adobe SDK.
It is much more likely that Sony's DRM ePubs will work in B&N's software. I tried to purchase an ebook from the sony store to try in the B&N reader, but I got an lrx instead of DRM ePub. I don't see anything in the store that says what format I'm buying when I purchase.
So one or the other:
1. Does someone have a DRM ePub from Sony that they can try in the B&N
eReader software?
OR
2. Does anyone know how to make sure the book you're buying in the Sony ebookstore is ePub?

Also, my apologies if this has already been beat to death around here. I did a quick search and didn't find what I was looking for.
Edit: The file I originally downloaded from B&N was in eReader format, not ePub. The file I downloaded from Sony was lrx. Until either bookstore starts actually selling books in ePub, this question can't really be answered.
