My user is member of the cdrom group. BTW I have no permission to browse my CD drive?! Okay, what’s going on?
You know the Vista bug. It takes longer to calculate the required time for deleting a file, then just deleting that file.
Do they have meaning?
In OpenSuse 10.2 and 11.0 My CD (DVD) drives belong to group ‘disk’, not ‘cdrom’. Adding the user to that group solves the issue for me. But you should search/post this kind of question in the hardware section (see forum rules). We’re not supposed to post help here.
Yeah, I know 
BTW thanks for your help. It was just an opinion, this is the reason why I posted it to Chit-chat.
