I'm having a weird issue here. The DVD-Drive is recognized and regular CDs are readable, but DVDs (talking about the regular burned one, not movies) aren't.
sudo lshw -C disk outputs (except for the hd):
*-cdrom description: DVD-RAM writer product: DVD-RAM UJ890AS vendor: MATSHITA physical id: 0.0.0 bus info: scsi@1:0.0.0 logical name: /dev/cdrom logical name: /dev/cdrw logical name: /dev/dvd logical name: /dev/dvdrw logical name: /dev/sr0 version: 1.00 capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram configuration: ansiversion=5 status=ready *-medium physical id: 0 logical name: /dev/cdrom
I did some checks but that device seems to be perfectly supported by the system. No external drivers needed. Some posts suggested editing fstab but the drive is found and regular CDs work. (In fstab are only the hdd and its swap partition registered).
libdvdread4 is installed too.
