Additionally, if the disks will not read, it's possible that the disks were never closed... This can be a much larger problem that may or may not be easily solved..
Thanks Cory. I tried the video lan player and could not get the install to work here at my office. The download seemed to work but it hung on the install and also asked what I wanted to open it with and gave me some options none of which looked appropriate. I will try again at home.
