Should be plenty fine on a 6 meg connection. I rarely had any problems on my 6 meg Uverse connection before I upgraded speeds. Then again with Uverse there is no "throttling" and I get my full 6 megs I pay for unlike when I was with cable. So it really all depends on your ISP and if you can sustain a solid connection. It doesn't cost anything extra to stream from Netflix if you're already a member so try it out. If you don't have Netflix you can get a free 14 day trial.
