this is the error:

I get a similar error whe running cdrecord as a normal user. Up until now I have been sudo'ing it but it's getting on my nerves, as if i have seen this before but can't remember the solution >=~|

put me out of my misery someone!

edit: I am a member of all the right groups, disk, cdrom etc
&& the common error is "cdrecord: Drive does not support TAO recording"
