Digiarty are old friends of Tech Support Alert, and we've featured a number of their media-related utilities in the past.
If you are in need of a utility that allows you to make a backup copy of a Blu-Ray DVD, the company is currently giving away free licences for a program that will allow you to do just that.
The software normally costs $49, but you can activate it for free until September 15th. Just head to http://www.winxdvd.com/blu-ray-decrypter, where you'll find the download link and the activation code.
I don't have access to a Blu-Ray disc or player, so I haven't been able to test this software myself. But I have checked the download with Virus Total and no virus or malware problems have been reported.
Please remember that this is a tool to allow you to back up discs that you have legitimately purchased. This web site does not condone software piracy.
