ripguardでDVDのリッピングが困難に

macrovisionの開発した海賊版DVD対策のripguardでDVDのリッピングが困難になる。現状ではDeCSSを使ってリッピングされた海賊版DVDがp2pに放流されているが，ripguardは現在出回っているほとんどすべてのDVDプレイヤーで使うことができ，リッピング・プログラムを使おうとするとクラッシュするらしい。

Macrovision says its new RipGuard technology will thwart most, but not all, of the current DVD ripping (copying) programs used to pirate DVDs.
"RipGuard is designed to... reduce DVD ripping and the resulting supply of illegal peer to peer," said the firm.
Macrovision said the new technology will work in "nearly all" current DVD players when applied to the discs, but it did not specify how many machines could have a problem with RipGuard.
