I've been using Rockbox on my 2GIG nano for a while, and I think its the only real good software for that iPod hardware ;-)
But I have one problem that's really messing me up: during playback I always get short gaps of 1s ... this happens 2 or 3 times per file ... and I really don't know how to solve this. It happens with long and short files, with mp3 vbr, cbr and with ogg. I tried smaller Playlist- and Dir-Sizes, I reformated the filesystem .. no help. BTW: the gapless playback for 2 files works great! And if the player stucks during playback, it's not possible to press a key or so.
Does anyone know what to do?
