What Should You Turn to for Decryption after Slysoft's Down

Since Slysoft hasn't been back completely yet as the payment and sales are not handled successfully, people need to access the DVD/Blu-ray they invested, there must be a solution, an excellent alternative of AnyDVD, or even a better option. Throughout the multimedia industry, there is no shortage of DVD/Blu-ray decrypter software. How to pick out the target you need and how to evaluate it not inferior to AnyDVD? There are several factors for assessment: public praise, maturation of technologies, stability in processing, speed in decrytion and the completeness of decryption. To have all the elements covered, there is a program well-deserved your investment.
