I thought it would be worth mentioning that Alcohol Software is offering a 40% discount on purchases of Alcohol 120% until December 23rd. Alcohol is an excellent piece of software for backing up games or DVDs. It has support for many popular copy protections. You can also mount images onto up to 31 virtual drives using Alcohol. Here is the announcement as seen at the Alcohol Soft store...
Reduced price! (For a limited period only)!
Alcohol 120% enables you to make a duplicate back-up to recordable media of nearly all your expensive GameSoftwareDVD* Titles, and/or an image that can be mounted and run from any one of Alcohol's 31 Virtual drives.
Purchase Alcohol 120% download version 126.96.36.19905 or boxed version 188.8.131.525 before December 23rd and receive a 40% discount off the RRP (valid only for single license purchase). This offer includes free updates and support.
