dvd device changes after new dvd inserted

[rhavenn]

Binary package hint: udev

Running Kubuntu Hardy Beta on x86. I only have a single DVD/CD device (Sony CD-RW / DVD).
I use my computer to watch movies. The initial beta worked fine, but after running synaptic a few times over the last few weeks the following problem has shown up.

If I boot the computer with a DVD in the drive it will create /dev/dvd correctly. However, if I eject the DVD and re-insert it or a new DVD the system will create /dev/dvd1 and kaffeine, etc... won't play as they can't find the device. Annoyingly however Kaffeine prompts to install libdvdcss which seems wierd??? But that's a different matter. The /dev/dvd device is removed completely.

Anyways, my /etc/udev/rules.d/70-persistent-cd.rules looks like this:
--------------------------------------
# This file maintains persistent names for CD/DVD reader and writer devices.
# See udev(7) for syntax.
#
# Entries are automatically added by the 75-persistent-cd-generator.rules
# file; however you are also free to add your own entries provided you
# add the ENV{GENERATED}=1 flag to your own rules as well.
# SONY_CD-RW_CRX320E (pci-0000:00:08.0-ide-0:0)
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:08.0-ide-0:0", SYMLINK+="cdrom", ENV{GENERATED}="1"
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:08.0-ide-0:0", SYMLINK+="cdrw", ENV{GENERATED}="1"
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:08.0-ide-0:0", SYMLINK+="dvd", ENV{GENERATED}="1"
# CD-RW_CRX320E (pci-0000:00:08.0-scsi-0:0:0:0)
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:08.0-scsi-0:0:0:0", SYMLINK+="cdrom1", ENV{GENERATED}="1"
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:08.0-scsi-0:0:0:0", SYMLINK+="cdrw1", ENV{GENERATED}="1"
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:08.0-scsi-0:0:0:0", SYMLINK+="dvd1", ENV{GENERATED}="1"
-------------------------------------------
I can fix the situation by changing the cdrom1,cdrw1,dvd1 to just cdrom,cdrw,dvd and /etc/init.d/udev restart
It lists this file as being auto-generated by 75-persistent-cd-generator.rules which doesn't exist . I don't know enough about udev to delve further.

Let me know what you need.

Created a separate bug #250232 to record the incorrect comment about 75-persistent-cd-generator.rules

I remember seeing this bug on hardy. Don't have much details now though except that in my case it was mplayer showing errors.

I am now using intrepid and don't see a problem there.

Sounds like we fixed this
