>BTW, how many tries did it take until you were successful?
I was having problems last summer when it was unusually hot - it sometimes took two or three attempts to install a VI collection. In the end the problem got more and more severe and eventually it became clear my PC's DVD drive was failing. I changed it and the problem has not occurred since.
Unfortunately when you're trying to install 80GB of data this kind of problem can be very time-consuming, but I doubt it's due to a fault in the VSL DVD's - however, if it is, I'm sure they will replace them.
