When you watch a DVD you bought or rented, you first have to watch a few warnings about being a criminal when you also show this DVD at school or to your grandpa or whatever... On a normal DVD player you can not fast forward this.

When you watch a downloaded DVD all this has been removed by some evil hacker. So you can just watch the movie without all this crap. _{Downloading is legal in almost all countries.}

So thanks to Disney and other large (and evil) companies we are now in the following, ironic, situation:

When you play by their rules you get "punished" by having to watch ugly warnings.

When you play by your rules your movie watching experience is not diluted with scary warnings.

The movie industry does not have clients anymore, they only see criminals...
