udev-115-5.20071012git.fc7 has its own persisten naming mechanism. Please edit: /etc/udev/rules.d/70-persistent-cd.rules ok, solved in my case by editing the 70-persistent-cd.rules

Description of problem: i have two dvd drives a DVD-Rom and a DVD-RW drive, but the symlink to /dev/dvd always show always to /dev/sr1 the DVD-RW and not to /dev/sr0 The DVD-Rom drive should be mapped as /dev/dvd and /dev/cdrom to /dev/sr0 The DVD-RW drive should be mapped as /dev/dvdwriter and /dev/dvdrw to /dev/sr1 therefore i created this 2 rules in the file /etc/udev/rules.d/51-custom.rules, but this didn't work after reboot.
