Code:

echo “sys.dev.cdrom.lock=0″ >> /etc/sysctl.conf

that is to ensure nothing stupid is preventing xbmc. failing that idk, it works fine here. A fix was merged ages ago for this.

when in XBMC you probably need to press play, I cant say I ever had non default data inside the dvd.

I managed to make the Play Disc button appear and work thanks to AVee and brownie's posts and this post by tesjo on the Arch Linux forum: https://bbs.archlinux.org/viewtopic.php?pid=941120
This is on XBMC running under Ubuntu 12.04. The problem seems to be that the /dev/cdrom symlink disappears after the first time you insert a disc. I think it's an issue with udev or Ubuntu rather than with XBMC.

To recap, I made two modifications:

(1) I commented out the line

Code:

+auto.master

at the end of the file /etc/auto.master so that now it reads

Code:

# +auto.master

Edit: this seems not necessary for me - it works with (2) only.


(2) I created a new file /etc/udev/rules.d/82-cdrom.rules as follows:

Code:

# Custom CD-ROM symlinks
SUBSYSTEM=="block", KERNEL=="sr0", SYMLINK+="cdrom cdrw dvd dvdrw"

The Play Disc button now appears automatically when I insert a CD or DVD.

Yesss... That works on two machines (XBMCbuntu on 12.04) here finally. Good work!

Yes, the "Play Disc" button appears now, but if I press it nothing appears...and if I going to video-->files, and click on "new" button (the dvd data, I think), directly list many folders (bin, mnt, cdrom, dvd, etc.).

I don't know what I have doing wrongly...

Thanks and regards.

tocinillo, from your earlier posts I understand that you're looking to access a data dvd with video files on them. The play disc button is not expected to work for that, only for a dvd in video dvd format. The folders shown under video/files look like the contents of your root directory /.
Try to go to the /media folder. Does your dvd show up as an entry there?

Yes, I'm trying to access a data cd/dvd. The "Play disc" appears in main menu, but when I press it nothing appears. if I going to video-->files, and click on "new" button (the dvd data, I think), directly list many folders (bin, mnt, cdrom, dvd, etc.).

I tried to open /media folder (insead Video-->files-->New (thats the dvd data) and when I opened directly list some folders: cdrom, cdrom0, dvd and usb1-7. If I try open cdrom/cdrom0/dvd folder, this appears empty.

Furthermore, If I close XBMC (Exit), and return to login screen (LXDE) I log again in XBMC interface and then the dvd data APPEARS correcly. This indicates me that if I login in LXDE the optical dvd/cd mounts correctly, but not in XBMC...

That mean that xbmc/your user is not added to proper user groups.

uNi

OK, mi username is htpc , how I add to proper group?

Thanks!

[un1versal]

First check what user groups its added to:

Code:

id htpc

It should be more or less depending on what you want access to.

uid=1000(xbmc) gid=1000(xbmc) groups=1000(xbmc),4(adm),24(cdrom),27(sudo),29(audio),44(video),46(plugdev),100(users),104(fuse)

In this case where is xbmc should be htpc

to add users to missing groups:

Code:

usermod --group audio,video,fuse,cdrom,plugdev htpc

and for good mesasure add htpc to users

Code:

adduser htpc users

Use sudo where it applies for permissions

Hi,

I'm having this same problem. I'm now not able to access CDs or DVDs. I had this working at some point, but after a reboot, DVDs don't seem to mount any more. I did the actions Phyr0 described earlier
- sudo apt-get install w32codecs libdvdcss2 libdvdread4 libdvdnav4
- added dvd -fstype=iso9660,ro,nosuid,nodev :/dev/dvdrw to /etc/auto.misc
- reboot --> does not work
- commented out +auto.master in /etc/auto.master
- created /etc/udev/rules.d/82-cdrom.rules with SUBSYSTEM=="block", KERNEL=="sr0", SYMLINK+="cdrom cdrw dvd dvdrw"
- reboot --> did not work
- added echo “sys.dev.cdrom.lock=0″ >> /etc/sysctl.conf
- reboot --> did not work

Can anybody give an hint what to do? I'm wondering if the problem is in having both /etc/udev/rules.d/70-persistent-cd.rules and 82-cdrom.rules ?

Thanks!

[un1versal]

Code:

$ sudo mount /dev/sr0 /cdrom/
mount: no medium found on /dev/sr0

There is nothing in there to mount in first place.

can you pastebin the result of

Code:

cat /dev

You could try to add a cd/dvd mount to fstab too, in addition read this since it appears to where some of the instructions in this topic came from

I have same problem. I tryed every single solution I found but without luck...

If I power on my HTPC with CD/DVD inside BEFORE power it the cd/dvd data shows correctly or if I logout/login to LXDE. In addition, I see that if I login to my HTPC remotely (NoMachine, that login automatically to parallel LXDE session) a popup appears, so the cd/dvd is detected correctly...

If I put mount dev/sr0 the cd/dvd is mounted correctly but in XBMC Sessions not....

Furthermore, I tried all solutions in fresh xbmcbuntu installation (under Virtual Box) and I hace the same problem, so the problem is in Ubuntu/XBMC, not in my machine. If I rembember correctly, I tried it with Archlinux and same problem appears, so I think that problem is XBMC...



Thanks and regards to everyone.

[un1versal]

IIRC this was fixed in XBMC but only after Eden release so its not part or xbmcbuntu.

Hi,

thanks.

Code:

$ sudo mount /dev/sr0 /cdrom/
mount: no medium found on /dev/sr0

There is nothing in there to mount in first place.

Should this do the trick?

Code:

sudo mount -t iso9660 /dev/sr0 /media/dvd
mount: no medium found on /dev/sr0

can you pastebin the result of

Code:

cat /dev

Code:

cat /dev
cat: /dev: Is a directory

Did you mean cat /dev/sr0?

Code:

cat /dev/sr0
cat: /dev/sr0: No medium found

I added to /etc/fstab

Code:

/dev/sr0        /media/dvd   iso9660 ro,user,noauto  0       0

By the way, I have booted my machine with a DVD in the drive, but it does not get recognized then. The reason I use the Live CD is that this way I managed to get the XBMC to work with my Asrock HTPC remote..

Hi,

ok, I got this working - kind of... I had in /etc/udev/rules.d/70-persistent-cd.rules

Code:

# This file maintains persistent names for CD/DVD reader and writer devices.
# See udev(7) for syntax.
#

Note: scsi-1

On the other hand:

Code:

$ dmesg | grep -i "DVD"
[    2.104060] sr0: scsi3-mmc drive: 24x/1x writer dvd-ram cd/rw xa/form2 cdda pop-up

Pointed to scsi-3. Changed all scsi-1 values in /etc/udev/rules.d/70-persistent-cd.rules to scsi-3 and did a reboot and when inserting the DVD it got recognized. How ever, the DVD does NOT get recognized every time I isert it, but I have to open the bay and re-insert the disk again and a again, and then at some point it get recognized.

Another interesting thing is that I don't see anything under /media/dvd nor mount does not list the disk even if it's being played. So, something works, but not as it should...
