Thanks for the help fella's.
Unfortunately, at this point I can only conclude it is a defective DVD.
I just tried it with an external DVD unit I have, free from heat issues, and the same thing happened. 4 times in a row.
Besides, the DVD player in my 2 gig G5 has never faltered, and in fact, has successfully loaded the 3 other Vienna VI libraries I own. And just a few days ago it loaded another sample library without incident.
I'll certainly be calling Ilio tomorrow morning, to see about a replacement disk. If there's anything else I could try, I'm all ears...
Hey, one thing I have noticed, that may be my ignorance, is that icon of the package.info on all my other Vienna VI DVD install disks is a white piece of paper with the corner folded over. Just like all the other content icons on the disk.
But on the Appasionata DVD, the package.info icon is a green box, with .exec on it, which is what I've seen before when it's a windows app.
Any chance that has anything to do with it?
