No company is more anti-piracy than the Disney Corporation. They also have unlimited funds to try to prevent their DVD's from being copied. They do what they can, but they know college students have little money, lots of free time, and are clever to boot, and they'll figure out a way around anything that annoys them like copy-protected DVD's.
It's one thing when somebody does what's called the 3 R's. Rent, rip, return. This is the guy who rents the video, copies it for his children to view, returns the video the next day, and that's that. Of course it's illegal but at least the guy isn't selling bootleg copies out of the trunk of his car. Whether he'd ever buy the video is debatable, maybe if he saw it in a bargain bin for $5 used he might, but forking out $20 or more for a new video isn't in his budget.
It's the folks who copy the video multiple times and sell them, either in-store, at swap meets, from the trunk of their car or overseas, some of the Asian countries ignore copy-writes, these are the guys to go after. They make lots of loot selling dvd's and cd's they have no right to. This is really stealing.
One of my bridge partners buys videos for $5 from a guy who illegally copies them and sells them to her, he comes into her hair salon with his wares but the quality is substandard. I've told her not to do it and I think she stopped. These are the folks the video producing companies need to stop, or try to stop. I think he's a one-man operation so good luck with that.
If the Disney Corporation can't do it, I'm going to guess that Sineplex can't either.
