Yes, /dev/scd0 disappeared after a recent upgrade (after 2011-11-17).

Running lshw *as root* says which /dev files can be used.
In my case:
*-cdrom
description: DVD-RAM writer
product: DVD+-RW TS-U633A
vendor: TSSTcorp
physical id: 1
bus info: scsi@1:0.0.0
logical name: /dev/cdrom
logical name: /dev/cdrw
logical name: /dev/dvd
logical name: /dev/dvdrw
logical name: /dev/sr0
version: D300
capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram
configuration: ansiversion=5 status=nodisc
I've chosen to use /dev/cdrom in case /dev/sr0 would be replaced
by something else.
