I had this problem on feisty beta. I installed the ubuntu-restricted- extras package and this solved my problem; after installing this package Rhythmbox correctly transferred files across to my ipod.
A dupe of this bug also seems to be here: https://bugs.launchpad.net/ubuntu/+source/rhythmbox/+bug/86920 -- Rhythmbox doesn't transfer music or podcast files to 2GB black iPod nano https://launchpad.net/bugs/87514 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
