I feel your pain. I hate DRM too. But, most BR/DVD manufacturers, aside from Sony (and others), aren't involved in content production. If they could, they would sell you a box that defeats DRM entirely, but they can't legally do that. They also have to "pay" Sony for licensing every player, they wouldn't do that either if they could help it. They want to sell you hw, they aren't the ones trying to make you mad. Lite-On, Pioneer, LG - they want you to buy, they don't want to screw you over. Sony would sell you a "play once" disk if they could get away with it (and they are trying).
I'm sure you know this, so I'll just stop at that. I get worked up about DRM as well, and the pain you have to go through to make a PC compliant. Yep, the pirates can pay for the tech to defeat DRM, for them it's trivial. So the whole DRM thing is a boondoggle, but try to convince a congressman of that - impossible..
For audio/visual cables there is a place on the net that is fantastic. I bought a 10m DVI -> HDMI converting cable for something like $12 USD. When it arrived I was shocked, it was military-grade with gold-plated contacts, as thick as your finger and I've been abusing it for years. I am so sorry I can't remember the name of the place, maybe someone else can help out.
Monster Cable (and Best Buy) should be sued for false advertising. The DMCA should be redacted as unconstitutional and everyone who voted for it impeached. That's my opinion...
