A number of things could be going on, but, given > the lack of details of the original post, there's no way to tell what. No more details were given. Because I had none. A friend, in another office. Couldn't read a DVD disc. At first I thought it was a DVD video, turns out it was a DVD data disc of some kind. that was unreadable on the several different macs they have with DVD readers on them. Knowing that it was a DVD data disc, not a DVD video disc. I hoped to verify that it could just possibly be burned in some format that is not readable by their macs. And tried to determine if maybe they would have better luck finding a Windoze box with a DVD reader, to see if it would work (which is what I suggested, before posting the question here) and as someone else posted.. it could be other reasons not even related to windoze->OSX. thanks for the replies.
