Is it possible that most subscribers to NetFlix are not copying the DVD's to build a library of movies?
There are a few very efficient programs out there, some of which cost a few bucks and one of which is free, if used with Nero, that can make a copy of a Macrovision encrypted movie in about a half-hour, presuming the use of 8x or faster recordable DVD blanks, which, in quantity, cost less than fifty cents each.
This is, to me, just like magic. I guess it's illegal as hell, but who's to know?
