They practically force us to download the AVI!!!! 
Exactly, and this type of 'interaction' takes place between the end user and the entertainment industry. When they'll discover that they sell less DVDs because of these silly warnings, they'll probably stop adding them. No politics whatsoever are required for this process.
And you can't even skip those parts. They practically force us to download the AVI!!!!
AVI?! You mean MKV h264/DTS 1080p BDrip! 
at any rate it doesn't really make me want to buy more discs.

They need to hurry up with that... but it doesn't matter, we're going from disc format to downloads/streaming more and more and those generally don't contain those warning movies. It took a while, but the industry is starting to understand we like to download and with services such as Zune (Xbox) and iTunes many people have no problem paying for it.
Half of the "piracy" problem is simply lack of availability, or more precisely, lack of availability in the desired format.
It takes a while, but the industry is starting to get it.
As for the pirate party, I briefly checked their site and that doesn't give me the idea it's just about "free downloadz". They seem to be a bit better organised than they initially were, and the party's name just seems off at this point. "Privacy Party" would probably be more like it.
The problem is that the Internet is way too international and you can't regulate that with a Dutch political party. In fact, anything that would be enforced (should they have the ability) by that party kind of contradicts what they want to achieve. For an example, just look at the weird cookie law... good intentions gone horribly wrong.

Yeah they might, ultimately. Unfortunately they dug themselves into a deep hole in the meanwhile.
Around the time MP3 file sharing was the hot new thing, the music industry could have stepped in, offer a legal version of their own with pricing & selection as the public wanted, and make lots of money that way. But they didn't, and thus Napster & co got big.
Then they could have done the same, but instead sued Napster out of existence. Thus other P2P file sharing networks (with centralized servers) became big.
They still had a window, but instead went after those other P2P networks too. Thus decentralized P2P networks a la BitTorrent became popular.
Then they went after individual downloaders, which left a bad taste in many people's mouth. With court cases making it clear that original artists get a tiny slice of the pie (if any), and nobody really needs record labels anymore.
As a result, P2P file sharing became so efficient, widespread & easy to use, that today it's extremely difficult for the music industry to come up with an attractive alternative. Which might not have happened if they had provided a legal alternative from the beginning. And they're dealing with customers who don't feel like doing business with them anymore.
Now watch them dig themselves out of that hole before they go bankrupt (wishful thinking 
). And repeat for games, movies, e-books etc.
