/dev/dvd missing

Hi,

on my install /dev/dvd got lost. I have to create a symlink to scd0 manually. Does anybody know the reason for this udev behavior or has a solution (pointers where to look at)?

Re: /dev/dvd missing

Thank you for bringing that up. I noticed that too, but have been too lazy to look into it. tongue

This seems to be the relavent thread: https://bbs.archlinux.org/viewtopic.php?pid=941382 I like Misfit's suggestion at the bottom, so I just added that to my /etc/rc.local file:

ln -s /dev/sr0 /dev/cdrom
ln -s /dev/sr0 /dev/cdrw
ln -s /dev/sr0 /dev/dvd
ln -s /dev/sr0 /dev/dvdrw

We don't create e.g /dev/cdrom for some time:

Re: /dev/dvd missing

Thank you very much for the prompt replies and valuable information!

So you tell me everybody who wants to use mplayer dvd:// needs to has his individual stuff in rc.local? Or do I miss something?

As a workaround you can use

mplayer -dvd-device /dev/sr0 dvd://

Re: /dev/dvd missing

I think mplayer's dvd:// protocol has nothing to do with the presence of actual /dev/dvd.

Re: /dev/dvd missing

For my own, i've created this file (82-cdrom.rules) in /etc/udev/rules.d :

SUBSYSTEMS=="scsi", KERNEL=="sr0", GROUP="optical", SYMLINK+="cdrom dvd"
