I rented a series from 1976 called I, Claudius from Netflix. The disks arrived today and none of them worked in either of my Macs. I thought that was weird, tried it in my DVD player and it works. So then I tried it again in my machine, nothing. Then I launched XP in a Virtual Machine and lo and behold the disk works perfectly. Some genius thought it was a commercial risk to allow a classic series that's over thirty years old to be viewed on a mac, lest somebody steal it. Which is exactly what I'm doing now, decrypting it in XP and then going to play it normally (the machine running the decryption has no speakers connected). This sort of DRM is exactly the reason that people steal software and movies. A casual renter or purchaser who tries to run this disk in a non-windowed environment is completely screwed. Interestingly enough there's an aggregate of one hundred people sharing multiple versions of this according to a torrent search engine, I'm sure if it worked as intended there would be less "piracy" going on. This is a bit of a rant, but who is with me in thinking such DRM is simply encouraging more piracy then it prevents? I truly don't mind it when it's seamless and just works, but when it refuses to play where all other disks play normally, . And why this of all DVDs?
