At first, I wasn't ok with this, then I thought about it, from a Canadian perspective, and now, couldn't care. Netflix here has to strip and compress everything to give the smallest amount of bandwidth per movie. Its horrid quality to due absolute garbage monthly bandwidth limits. Here you cannot rent discs by mail with netflix. There are a few online companies you can however. Netflix and other companies have taken a huge chunk of disc sales apparently. Its nearly impossible to find a video rental store in my area, they all went out of business. Piracy was supposed to have killed hollywood years ago, clearly that didn't happen. Hollywood and recording studio's have spent the last 10 plus years trying to stop piracy rather than embrace the online, instant access. For those that really want the HD audio stream, Hollywood just pushed some to downloading their content in the not so legal fashion, rather than rent, and support the larger industry itself.
Lets also be realistic, a great portion of the population most likely wouldn't notice the missing HD track, because they don't use it in their home. I bet the numbers who don't would be rather large. Someone earlier mentioned release day prices with DVD's, used to be 19.99 or so. Yes, they did, and after that, prices went back to pretty much to what they are now. With that being said, blu ray prices seem to fall a lot faster than DVD prices ever did, even TV shows at least here. I often pick up movies around the 15-20 mark about a month after release.
Hollywood is trying to get every penny they can, because they feel piracy is hurting them. It is, and it should. Hollywood failed to keep up with what consumers want, and how they want it. Hollywood believes they still call the shots. It is sad they have not clued in. For example, that nice little digital copy they give you when you buy a blu ray, that copy is SD. Why would I want a SD copy of a HD movie? I have less than a year to get it, sometimes less. I had a month for a title I bought a week ago, as it was almost a year old release. I still buy the physical media, but I usually rip it to a hard drive before I even watch it, so it can be watched anywhere in my home, by anyone.
This is nothing more than Hollywood trying to grab every last cent they can, power to them. Evenutally, the big studios will either adapt, or go broke. More and more people turn to piracy because they are just sick and tired of all the crap thrust upon them. All the warnings, all the controls or lack of, etc, punish the buyer, that seems to be Hollywoods take.
