DVD mounting issues in Mythbuntu (and Xubuntu)

Zeedok · 03-22-2009, 08:46 PM

I have just received a new Mythbuntu system which I am trying to whip into shape. I have a few little irritations, one if them involves the DVD drive.

My system:

Antec Micro Fusion 350 HTPC Case
Intel Core 2 Duo E8400 CPU 3.0 GHz
Gigabyte GA-EG41M-S2H Mainboard
4GB DDR2 PC6400 (2x2GB) Dual Channel RAM
8X Dual Layer DVD+RW + 20X DVD+-RW + CD-RW Combo Drive
1TB 7200RPM SATA HDD
512MB NVIDIA Geforce 8400GS
Gigabit Ethernet
Hauppauge Nova-T-500 MCE Dual DVBT SD/HD tuner
Cordless Keyboard & Optical Mouse
Mythbuntu 8.10 with Xubuntu desktop
When I insert a DVD it is not mounting correctly. If I mount the drive manually (or by using Mountmanager - which I found in the repos) I can then play it (I have all the codecs etc, so that is not an issue). At other times I can't seem to mount the drive properly (I'm sure it is a permission problem), but if I reboot with the disc in the drive, then it mounts and I can play it in VLC or in Mythbuntu itself.

My current FSTAB line looks like this:

Code:

/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec 0 0

Which I copied from my laptop (where the DVD drive behaves correctly - ie when I enter a DVD data disk it pops up ready to read the files, or when I enter a video DVD it asks me whether I want to open the disk with Totem).

What am I missing - is there an error in my FSTAB? Is there another config file that I need to check/edit? Could it be a installation issue (eg a cable selection on the drive itself - I only have one drive)?

Thanks in advance for any suggestions and help.

insert utf8 after exec,utf8 0 0
See if it makes any difference

I actually recall having a problem on opensuse 11.0, where my user account want not part of a certain group or didn't have the appropriate permissions.

Try going into administration>users and groups and highlight your username, then click properties. In the 'user privileges' tab there is and option to "use cdrom drives." Make sure that is selected.

Hope that helps.

I think I have already tried this, but I'll check tonight. Out of interest, what does this do??

I'll check this one out - not having privileges would make sense to me. When I mount as sudo the drive behaves normally, it also works fine if I boot the computer with a disc already in the drive - would this be explained by a lack of user privileges?

Thanks for your suggestions, I'll let you know how I get on,

Yes, it sounds like an issue with permissions. I've had instances just like yours where by default, filesystems would auto mount and give me read/write access if plugged in before booting, but if I hotplugged after already logging in, I would get a 'permission denied' error. This was with an external hard drive, but they're just volumes all the same.

Well, I had a look and the "cd-rom" box was checked so that is not the problem. On the other hand, I added the utf8 and it seems to be behaving correctly - so far.

Thanks for your suggestions
