Macrovision 7.0 is the next target to defeat........................ Subject: Re: Possible method to defeat Macrovision 7.0 From: "Curt David" <CDavid@noporkproducts4me.SRSales.com> Date: 1997/10/21 Message-ID: <62id0k$dmg@newsops.execpc.com> Newsgroups: alt.video.dvd,sci.engr.television.advanced,sci.electronics.misc [More Headers] I don't really disagree with you in principal. I'd be tempted to do the same thing. But, how old are your kids? My four year old does a good job handling CD-ROMS. My 2 year old probably wouldn't be so good though. The trouble with sticking with VHS only is that these tapes degrade and lose quality rather quickly. With Disney titles you never know when it will finally break and if you can replace it. I guess you could make the same case with DVD, but if your kids are 4 and older, then you should be able to teach them to handle the discs carefully.
