Basically they are complaining the the DMCA makes them responsible for policing their own content at their expense.
It's not the government or the ISP's job to monitor and/or determine the usage of the content available on the internet. Were I to publish a game, for example, it would then be up to me as an individual to research, inspect, and determine if anyone is infringing on the copyright of my game. Just because they're a large entity doesn't mean they should be exempted from the same issues facing the individual content owners.
Why should the ISP's be forced to swallow the costs of such a manhunt, when they receive zero benefit from the search, it costs them money, and it displays them negatively in the public light such that their brand is devalued, however slightly.
Essentially, content owners should be, and are, responsible for making sure that everyone who uses their content is abiding by their specified licenses, etc. If you're complaining about the costs that you incur whilst enforcing your licensing model, and want the government to help out, perhaps you should re-evaluate your licensing model. Of course, that particular dead horse has been beaten so severely, at this point, to be unrecognizable.
Big problem: We only have so much helium on the planet.
We do, however, have plenty of hydrogen. That could be used instead of helium and we can send as many balloons as we wanted without a whole lot of fear of "running out" of the lift fuel.
The point of HD is high quality, right?
Exactly! And the Blu-Ray format was invented to allow more storage on a physical disc media. Thus, you have the storage available to put an entire movie in High Definition on it(~10 - ~30Gb).
I have the fastest available broadband in my area(18Mbps down). To download an entire high def movie in that size would take significantly longer than I would want to wait in front of my television for it. I bought my Blu-ray player for the quality. If I'm going to be forced to download the same content, I expect, and demand, the same quality.
Also, let us not forget about the fact that a sizable portion of the US is still running on dial-up, so downloading a high definition movie is completely out of the question.
Unless the content providers are willing to invest heavily in the broadband infrastructure of the country then physical media like Blu-Ray is here to stay, at least for the next several years.
