I had a NetFlix membership for many years, BEFORE they were doing streaming video, and found their service to be very good. I quit them once I realized that I owned way more DVDs than I could possibly watch in the next two years.
I used NetFlix to "test drive" movies and determine if they were films that I wanted to own, rather than buying them just to find out that I would never watch them again.
I will grant you that they only carried the "mainstream" films, but that never bothered me, since I'm a "mainstream" kinda guy (I make no apologies for this). There are other outlets for the less "mainstream" films, so, I don't fault NetFlix for their decisions; after all, they are a business trying to make a profit (not a dirty word).
I am not interested in "streaming" video to my PC. First of all, I don't want to watch movies on my 21" monitor when I can watch them on 1 42" plasma display. Secondly, I only have a stereo sound system on my PC, whereas I have a full 7.1 sound system on my plasma TV. Sorry, but I just cannot understand anyone wanting to listen to any movie in stereo that could be watched with 5.1 or 7.1 surround sound. Thirdly, watching movies on my PC doesn't provide the same experience (environment, comfort, ambiance).
I know....I could stream to my TV, but I'm just not set up to do that. I have the network connection, but not the service, and just don't see the cost benefit for signing up for it. Like I said, Ii have too many unwatched DVDs to even think about it for now.
