DVD drives can't read discs

[jwdove]

I went to back up my Starsky & Hutch season 2 box set and the first disc did fine. When I put the 2nd disc in, the computer can't find any disc. Powerdvd can't find it . Dvd decrypter and Dvdshrink can't either. It plays fine in my stand alone player though. Occasionally powerdvd will come up and play the teaser at the beginning with the options. Then select play and it can't find any disc again. I transferred the drive to another computer and got the same thing. A friend borrowed disc 3 and we tried playing it on his computer with Powerdvd and it did the same thing. I haven't tried discs 4 & 5 yet. My drive is an I/O Magic bought a few months ago. Why can a standalone have no problem with these discs but a computer not recognize them? Is there anything I can do to backup these discs? I backed up the 1st season without a hitch.
