Hi Dale, Somewhere buried in the rockbox site exists a list of file types that Rockbox supports. To put it simply just about any file type which isn't protected. The devs refuse to support any type of DRM protection plus I'm sure they don't want to invite any legal attention either. I personally use OGG which is smaller than MP3 but has better sound and Storm recently mentioned OPUS which I'm currently looking into.
