As if that weren’t enough damage to have to control, a pair of European programmers announced on the same day that they were able to bypass the copy protection on DVDs because a DVD software licensee failed to secure its decryption key. The licensee: Xing Technologies, which RealNetworks acquired earlier this year.

Angering consumers and studios in a single week, it seems, takes a RealEffort.
