Above is true. I had 1 to 1.5 mbps DSL when PlayOn started streaming Netflix to the PS3, and it was very choppy. Called my phone company who claimed they had no faster speeds, but with some threats to switch over to cable, they suddenly realized that they could give me 3 mbps speeds. No problems with SD streaming now, which is pretty much all I intended to watch via stream anyway (TV on DVD and such).
Two things are infinite: the universe and human stupidity. And I'm not sure about the universe. -- Albert Einstein
