Google's help page just says

Images in our PDFs are highly compressed
but Adobe's Digital Edtions FAQ is a bit more forthcoming:
Quote:
Why don't some Google Book PDF files work with Digital Editions?
Google is using JPEG2000 image compression to compress certain kinds of color-based page images, and this format is not supported by Digital Editions 1.0.
Google says that xpdf (with JBIG2 patch) reads its PDFs, so there is a chance that an updated ipdf could too.
