problem : can not read newly burned DVDs (DVD-R, DVD+RW) ? I can read normal DVD - cdroms, but . I tried k3b - nerolinux - tkdvd etc. same thing ? I can read the same DVD in winXP ! :-} .
my fstab look like this :
/dev/hdc /mnt/cd auto ro,user,noauto,unhide 0 0
/dev/hdc /mnt/dvd auto ro,user,noauto,unhide 0 0
/dev/floppy /mnt/fl vfat user,noauto 0 0
I running all the last updates and 2.6.17-ARCH.
no problems with norm. CD-roms !?
any clues ?
If you can't crack it then hack it !!

Try reading dvd's as root. If you can then your probably not part of the Optical group. In that case...
usermod -a -G optical username
That should add your user to the optical group. Then logout of your username and then back in, and try giving the dvd a try.
Other than that i'm not too sure. It seems weird that its only some dvd's, are you sure its not a problem with the drive in some way?
Offline
whats on the DVD's /CD's ? and are they single or dual layer?
are you aware of the difference between say a data cd and an audio cd with regard to mounting or playing direct ?
Offline
Thx for your reponds
user is in the "optical" group so that's not it, And it used to work before 2.6.17
Yes, this is Data dvd and I know one can't mount a audio CD only play it from a progz.
tried mount as root first : #mount /mnt/dvd - did not work! then mount -t iso9660 /dev/hdc /mnt/dvd -> YES it worked !?
and now I could mount as normal user to !?
Now I notice that
#lsmod gave me
msdos 7552 0
udf 68612 0
nls_cp437 6272 2
vfat 9856 2
fat 40732 2 msdos,vfat
sd_mod 14848 3
isofs 28736 1
zlib_inflate 14848 1 isofs
ahhaa I see they were not loaded before, so that the problem. Only root made them load
So I guess I have to reg. them in /etc/rc.conf
is that why my DVD burning was going so/unstable bad too ?
still there is some voodoo...
This DVD I can NOT read but it reads fine i winXP ??

I am having the same problem. My user account is in the optical group. I had to become root to copy the data off of the cd. so, i am having the same issue. the cd i was trying to read was quake4. i was trying to copy the pk4 files and the damn thing wouldnt mount... I dunno.

Try reading dvd's as root. If you can then your probably not part of the Optical group. In that case...
usermod -a -G optical username
i added myself to the optical group, and when i run "groups brian" as root i am able to see optical in there, but when i run as myself (brian) the command "groups" then i dont see optical.
Offline
@ briancurtin: Have you logged out of all active sessions or rebooted since you added yourself to the optical group?
@kahazdar: where are you trying to read the disk from? is this direct access to /dev/dvd or have you mounted it via some method
@BlueThumb: the "capability" module may need to be loaded to fix your burning problem. i never have had to use it but i rememeber something about loading it if you have problems..
it also seems like the dvd you cant read may be mounting with the wrong filesystem type perhaps?
hdc: media error (bad sector): status=0x51 { DriveReady SeekComplete Error }
hdc: media error (bad sector): error=0x30 { LastFailedSense=0x03 }
that would lead me to believe its a bad burn of the dvd, but if it reads in windows i'm not too sure.. i'll keep thinking and hopefully i can come up with something

Hmmm... I still have this DVD problem I tried to make a new DVD-r in K3b with iso level 3 and in DAO, it burned right and I could mount it, play abit and then it hang !! I got in dmegs.
ATAPI device hdc:
Error: Medium error -- (Sense key=0x03)
Unrecovered read error -- (asc=0x11, ascq=0x00)
The failed "Read 10" packet command was:
"28 00 00 00 09 d0 00 00 40 00 00 00 00 00 00 00 "
end_request: I/O error, dev hdc, sector 10048

Buffer I/O error on device hdc,
so it looks like some reading errors .
I found this link on :
