Hi
 
So been playing about with rockbox.  Like it except for that fact that it doesn't seem to play m4b files for me.  Of course what do I have a lot of? M4b.  Don't really want to batch convert the lot (they are all nicely tagged audiobooks) so are there any other options?

Cheers

From a quick search an m4b file is the same as an m4a file, just named differently.  Does changing the extension work?

M4B is in fact the same as M4A, and should "just work".

Thing is you can put all kinds of strange formats in M4A/M4B, and of course also encrypt them.  Encrypted audio will never work in rockbox, and if they're not AAC/ALAC its doubtful rockbox will have a decoder for them.
