Do you have Netflix Ondemand?

What are the requirements for internet bandwidth? Is 1.5 Mbps enough? We just bought a SERIOUSLY fast router for streaming content from Netflix ondemand to our new LG Blu-ray player (BD390 I believe), but even still I'm concerned 1.5 Mbps isn't enough for smooth playback. What are some gripes you have? Are TV shows available? What is the image/playback quality? Is it really INSTANT? Thanks!
