Description anlar 2004-07-09 12:34:22 UTC

I am using 2.6.7 with udev, I plug in my usb dvd-rom drive the /dev/sr0 gets automatically created. Even though my normal user account is in cdrom group, it can't access sr0 properly (via /dev/dvd naturally) for watching dvds. (The libraries xine/mplayer/etc use for raw accessing dvd) 

I just scratched my head for almost couple hours before checking the most obvious.. Please check and tune the defaults accordingly if I am not the only one.

Reproducible: Always
Steps to Reproduce:
1. Plug in usb dvd-rom drive
2. Launch xine/mplayer


Actual Results:  
Error messages about the dvd reading&decrypting libraries being unable to access
the device /dev/dvd

Expected Results:  
Played the dvd.

What is the permission that is set on /dev/sr0?

Comment 2 anlar 2004-09-22 09:44:58 UTC

As the new permissions seemed sticky and if I deleted the node at least the current scripts would give it proper rights, can't reproduce anymore.
