Is this some kind of copy protection? Without looking at errors I would recommend this: find CD only optical drive, and read CD on it (and maybe make disk image if it is legal to make backup image of content sold to you in your locality). The reason is pure physics: laser heads used for CDs and CD/DVD combos (and Bluray, - the last will be using DVD part of optics) are different, and sometimes CD/DVD reader that has sharper beam has less success reading CDs (especially older/aged, etc).
