I have the SIMON AND SIMON complete set on 17 discs


BUTTTT several discs have issues

7 of them--- they have menus with titles BUT only title # 1 will play
and it locks up at the end---- if i try to play title 2, 3, 4, etc
they do NOT play

the computer shows data on those titles, BUT they do not play, u cant FFWD to the next chapter, they are just defective
No matter what--- ive used all programs, they dont work
they dupe fine, but even the dupes wont play
