No problems with playing DVDs as root user. How do I change permissions?

I tried with udev rule:

/etc/udev/rules.d/82-cdrom.rules
SUBSYSTEMS=="scsi", KERNEL=="sr0", GROUP="optical", SYMLINK+="cdrom dvd"

but it's not working

Remove yourself from the optical audio and storage groups (at least). These can cause issues with systemd.

Thanks for the reply.
I removed optical and storage from the groups, but there's no effect.

video should go as well - see the systemd wiki for a full list of obsolete groups you no longer want to be in.

EDIT: Is polkit installed? Is your login session active?

So

wheel bumblebee vboxusers vboxsf users

polkit 0.112-1
polkit-kde 0.99.0-2

3.11.6-1-ARCH

systemd 208-2

Yes, login session is active.
I have no idea why, but now I can play the original purchased DVDs and music CDs, including my own created music CDs. But still I can not play my own created DVDs [created with another linux distro-disc is TDK DVD+R]. Files on these DVDs are m2ts.
FWIW, in Virtualbox I installed Windows 7 and no problems with playing my DVDs. Also, no problem with playback on Sony PS3 ??

Otherwise, no problems as the root user

If it is that specific, I really have no idea. Something weird with a udev rule, maybe?
