What's My DVD Licence Date?
This article shows you how to find out if the DVDs that you have been given are up-to-date. This information is helpful if you are encountering problems and need to contact technical support.
1) Take the DVDs out of their casing. There should be information printed on the front.
2) The licence period for the DVD is shown across the bottom.
If you do not see any licence information then your DVDs were produced pre-2011. The resources on them will have expired - see this article for information on renewing them.
