Reply: I wouldn't say "absolutely"... it actually isn't "absolutely" illegal in some countries. (I mean, of course it is in the US, but I'm talking about other countries.)

But if you upload it for the purpose of making money, then yes, it is pretty much illegal in every country. Copyright is only there so that credit can be given where due. Companies are only exploiting this for the sake of money. (Of course, if you were to steal a DVD or something, then yes, it would also be illegal. But "copying" is not the same thing as "stealing". If you downloaded a copy from the Internet and then ripped the original copy off the person, then that would be "theft" by any North American definition.)
