Creating a new disk inage

Question

I am trying to make a new dvd from another one and in disc utilities when new image is clicked the error message tells me "permission is denied. " If I click, verify permissions, before clicking New Image it tells me"Not available because the selected disk is set to ignore ownership." The disk I am trying to make a copy of has an allowance of 100 copies from the author.
How can I fix this??? Also my disk self ejects sometimes 20 seconds after I insert it.
