Not able to listen audio books in Rockbox

[weyman]

Model Sansa c250R
Rockbox 15791
Sansa firmware 1.0.2.65

I installed Rockbox today; everything works great except the four audio books do not work.  When I select a book, it comes on for a few seconds and then goes off.   The four books are all protected audio books from two different library systems.  They work on the Sandisk firmware but do not work on the Rockbox firmware.

Is there something I need to do to make the books work on Rockbox?

Thanks

Rockbox can not, and will not, support DRM.
This has been recently discussed in these forums, and long stated in the wiki.

All well and good to say DRM material is not supported - but DRM material should
not hang Rockbox - which it does currently.  I have to power off my Sandisk E280
after trying to open a library book.

Suggest a way to accomplish this, and I will consider implementing it.

Not knowing the file structure of these library books, or where it is hanging, I am not
qualified to say.  Is there a flag in the FAT directory entry you can check,
or in the first couple of bytes of the file?

It would be perfectly acceptable to put up a dismissable alert saying
DRM files not supported. This would beat the never-ending Loading indication.

I made a quick test using some music I just ripped (to protected WMA), and there was no crash on my Sansa e200. There was a brief noise when attempting to play the tracks, but other than that, it quickly gave up on decoding the files.

Lear,

Could you give me one of your protected files?  It should be possible for the WMA codec to identify and reject encrypted tracks at the metadata-reading stage.  This way, Rockbox wouldn't attempt to play them, and they wouldn't misleadingly appear in the database.
