I don't know why people are having issues with streaming, I've gone through about 3 full TV series they have on there (what little they actually have every season of) and thus far no problems... I guess it's my blazing fast internet (thanks comcast). I don't really do the DVD method anyway (I've had one DVD since like March and fear sending it back because I'll just get another in the mail to sit and collect dust). My fix, whatever they don't have on streaming instead of waiting 2-4 days for the snail mail I just BT it, watch it, and if it's good throw it on the ol 2TB HDD or delete if I don't like it. I'd rather wait 10-20min for a movie to download than 2-4 days for the mail. Whatever, I'm switching my service to streaming only.
Also, does anyone remember that press release netflix issued a few months ago where they wanted every movie/tv show/etc to be on Watch Instantly? I think they said by July 2012 the whole database should be WI.
