I started having the same problem that prevent me to listen to my music some days ago with Ubuntu Hoary.
A mount command show: /dev/sda1 on /media/IPOD-1GB type vfat (rw,nosuid,nodev,sync,noatime,quiet,uid=1000,gid=1000,umask=077,iocharset=utf8) This mount is done automatically by the system. I can confirm that unmounting the iPod and mounting again by hand the with the option "shortname=mixed" works and you can listen to your music in Rhythmbox. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
