Bitrate on all streaming is still too low for me really. Even with netflix and amazon instant. I especially notice it when panning or during dark scenes. I also avoid torrents or peer2peer anything, like the plague.
There are also people who share movies via plex. 1000s of them in HD. Although I think they charge a couple of quid a month. I'll stick to my old school methods for the time being. Fibre from end to end will probably be the end of broadcast TV.
My problem is I am a quality snob. I can't get enough of it. If I can notice the difference, I obsess over the poor quality. I haven't been able to watch broadcast SD or DVDs for about 3 years. It's what stopped me using my IPTV system, which is superior to SD, but inferior to HD.
