Of course it is not illegal if you make a copy of your own DVDs...it's a backup. But you may not use it, you may not show it, you may not give it to someone...you MAY use it if your original DVDs is broken. That's all IIRC, but I'm not a lawyer. You can enable Macrovision in DVDSP. But if you make a "backup" of your DVD and you turn off Macrovision, it's illegal since you changed something!
But I don't care! I am buying the DVDs I want. Most of them are bigger than 4,7 gigs anyway and are not worth the hassle of ripping the video streams and audio streams, creating a menu in Photoshop and burning them onto a 10$ CD-R disc. I admit, I am making illegal copies of DVDs...of DVDs you can't buy in Germany! Anime DVDs which are only available in Japan. Do I feel bad about it? No. I have more than a hundred original DVDs, so I really don't care if I make a copy of a DVD of a friend which you can't order here in Germany. If something is available here, I have no problem with paying money for it. If not, I copy it. This is not legal, this is not good, but that's my attitude. Most of these "original" DVDs are illegal bootlegs anyway, and anybody who ever was in Japan, knows what they think about breaking copyrights. Ever walked into a store where EVERYTHING is copied? I've seen them both in Osaka and in Hongkong, China. Stores FULL of illegal copies. Software, movies, garage kits...does the government care? No. Do the companies which hold the copyright care? No. Why not? Don't know, it's a rather strange attitude over there...
