Trouble with DRM ePub
I downloaded one of the free ePub eBooks available at BooksOnBoard and I used Adobe Digital Editions to transfer it to my 505. When I go to try to read it, I get it saying it's only 1 page and then I get a page error. What am I doing wrong?

If anyone would like to try this same ePub eBook, then please do. It's free and the link to it is... http://www.booksonboard.com/index.ph...01840&v=buynow. The ePub edition is the free edition.
If anyone else can get it to work, please let me know. |

I'm a bit confused though on what is ePub and not ePub. I thought those would have the ending .epub, but this file was called something else I think .etd ..?? Zevs |

I had to download it using Internet Explorer. Then it downloaded fine and showed up in Digital Edition. I then tried to copy it to the 505 and it seemed to copy fine as I can read the copy from within the reader using eBook Library or Digital Editions. But when I use the reader itself, it doesn't work.

I took a look, and this book isn't going to work on the current Reader firmware until the publisher creates a new version. I checked Adobe's "EPUB Best Practices Guide" again and it explicitly notes that ADE will only handle contained files which are less than 300k uncompressed / 100k compressed. The DRM layer makes the ZIP compression level 0% (will e-book vendors start doing compression at the DRM layer?), leaving the compressed file size of the main book body well above ADE's limit.
I'd suggest e-mailing your the e-bookstore and/or the publisher to alert them of the issue. -Marshall |

I assumed that this meant 300K uncompressed (with the compressed value as a guideline), but does it really mean the smaller of 300K uncompressed and 100K compressed? I can't see why the compressed size matters, unless DE stores the ebook in memory with compression.

So each individual xml file has to be a grand total of 300k, but the total ePub file can be large?

ADE should fallback to a a minimal CSS rendering mode (with support for say bold, italic, justification and nothing else) for larger files if displaying large files is impossible.

As an aside I tried a Secure PDF and it was viable on the Reader. =X= |

That would certainly be better than an error which doesn't tell you what the real problem is! OTOH, EPUB support with arbitrary limitations is certainly better than no EPUB support at all.
