Can't play dvd (no /dev/dvd available)

[Risto H. Kurppa]

UPDATED DESCRIPTION:
####################
I have two optical drives, a CD/RW drive and a DVD drive.

In /etc/udev/rules.d/70-persistent-cd.rules the CD/RW-drive is binded as /dev/cdrw and /dev/cdrom in and the DVD-drive is binded as cdrom1 and dvd1 - even though there's only one DVD drive. This causes programs, for example Kaffeine, to fail play DVD's from the DVD drive.

So changing /etc/udev/rules.d/70-persistent-cd.rules to mount CDRW to cdrw and cdrom1 and DVD to cdrom and dvd thigs started working again.

It think this has nothing to do with Kaffeine so I'll try to change the description etc in this bug report respectively...

ORIGINAL DESCRIPTION:
########################
Kubuntu 9.10 with medibuntu, partners & backports activated, upgraded. I installed Kaffeine (as Dragonplayer's a bit limited..) to play DVD:s, but it won't work:

start kaffeine
press 'play DVD'.
stdout gives me:

gs@utberg:/dev$ kaffeine
gs@utberg:/dev$ libdvdnav: Using dvdnav version 1.1.16.3 from http://xine.sf.net
libdvdread: Encrypted DVD support unavailable.
libdvdread: Can't stat /dev/dvd
No such file or directory
libdvdnav: vm: faild to open/read the DVD
libdvdnav: Using dvdnav version 1.1.16.3 from http://xine.sf.net
libdvdread: Encrypted DVD support unavailable.
libdvdread: Can't stat /dev/dvd
No such file or directory
libdvdnav: vm: faild to open/read the DVD

and I get a popup telling me "Cannot find input plugin for MRL [dvd:/]"

/dev/dvd doesn't exist. I can create it manually but it won't help much as I don't know how to make DVD appear there.. Also Kaffeine doesn't have the settings menu item there -> I don't know how to tell Xine to look for /dev/scd0..

sudo ln -s /dev/sr0 /dev/dvd seems to help.. No idea why this is needed. Either kaffeine should point to /dev/sr0 - or /dev/dvd should exist..

Changed away from kaffeine, I think udev is a better guess..

Remove the /etc/udev/rules.d/70-persistent-cd.rules file to regenerate it

It also affects Mythbuntu 9.10 with patches. I did the installation a couple of days ago, tested DVD playback successfully right after the installation, now it wouldn't work. After changing the DVD player in Myth to be /dev/dvd1, it again works.
