You can force HD on Netflix!?
How did I not know you could do this?! Am I the only one who didn't know? If so, don't mind me and my excitement.
If you don't want to click the link,here's the long and short of it: If you hold shift+alt and click on the Netflix player (not in full screen) you get a silverlight menu box. From there you can go to the stream manager and manually lock in the bit-rate Netflix will use. The higher bit-rates = HD. It may take a couple of seconds to get enough buffer at the new bit-rate to jump up to HD, but it worked beautifully for me.
PS: I wasn't exactly sure which forum to post this in, but I use a Windows PC so I thought this one would do.
