Hello there!
I have exchanged my Sony DVD reader with a Plextor PX-116A and also installed a Plextor PX-716A DVD writer. When I put a burned DVD into either one of these drives they show up on the desktop, but when I open them, they are seen as empty (blank) disks. I can however mount them manually as my normal user and go to the mountpoint in a terminal. Only there I can see the contents of the disk.
Other times I can't even mount the disk at all. All this only happens with DVD's, not CD's.
My /etc/fstab entries are:
/dev/hdc /media/cdrecorder auto pamconsole,exec,noauto,fscontext=system_u:object_r:removable_t,managed 0 0
/dev/hdb /media/cdrom auto pamconsole,exec,noauto,fscontext=system_u:object_r:removable_t,managed 0 0
I'm running Gnome on FC3 x86-64, fully updated.
Kind regards, Angelo
