Alan - Netflix lets you stream some material in High def - it's a little better than DVD quality, not as pristine as a blu ray. Audio (for now) is in stereo, although Netflix has recently gotten a license to stream Dolby Digital plus with some oftheir high def offerings.
The Insignia Netflix interface is better than the Samsung interface (strange, given the "budget" nature of the Insignia players). But, the Samsung also lets me stream audio and video from my home PC to the TV, wich is neat, but a little cumbersome.
The stream from both players is as good as what I get from the computer. It's definitely a mature technology, and very effective, even with wireless.
