Same here with the dislike of the Silverlight player switch. A while back I went to log in for on Demand playback after reinstalling the OS on a computer and it gave me some kind of error message when trying to get to the on demand video and said that upgrading to the Silverlight player would solve it. From then on my other two computers started using Silverlight for on demand and the picture quality went down significantly vs the old WMP implementation. This makes me very unhappy.
Whereas I would actully sit and watch something, on demand, on the big TV before it is now totally unacceptable as anything more than having it on while I am doing other things (usually now I will have it on in a small window of the second monitor while working on photos in the den, etc.) But it is too choppy, too much tearing in pans, and the all out PQ is too bad to actually sit and "watch" it anymore. And that is sad.
I still like Netflix, it beats having to go to Hollywood to pick up and drop off discs, and even with the new price increase for Blu Rays, I feel their pricing is still a good deal, its just sad to see the their on demand regressing.
Lastly, BlockBuster can die of gonorrhea and go straight to hell. I will not miss them one bit. I always felt dirty, like I needed to take a shower, after coming out of one of those stores. The people they employed were creepier than SIDS.
