Macrovision is the unnamed company, apparently. And it seems they did this in a preemptive strike, as their "rip guard" is about to go live. Since Arccos was defeated within days of it's release, I guess Macrovision got jumpy and decided they better shut dvd decrypter down quick.
But they'll puff their chests and say how unbeatable rip guard is. Riiight. I give it less than a week after release, and at the very least, AnyDVD will be updated to break it. I'm waiting until AnyDVD can bypass rip guard before I decide to purchase it (even though it's free updates for life). As long as AnyDVD is running in the background, decrypting on the fly, DVD Decrypter should be able to continue to rip any future dvd releases without any problems.
That is, of course, only if someone doesn't take up the freeware torch between now and then with an all-in-one solution like DVD Decrypter.
As for DVD Shrink and how it works with Decrypter, The Forgotten was released with the new Arccos encryption. I believe it was the first one. DVD Shrink 3.2 failed to even analyse the disc. But I ripped it to the hdd with DVD Decrypter 3.5.2 as an exact duplicate of the dvd without even a hiccup ... minus encryption/macrovision/region lock, etc. Then took it into DVD Shrink and proceeded to make it fit on a dvdr
