For those considering Roku vs BR player with streaming capabilities...
Not sure if its been mentioned yet, but the quality of streaming vs an actual disc is horrible. I had my LG BD370 hardwired to the internet for the netflix streaming and 1) the audio is only 2 channel and 2) the picture quality is somewhere between VCR and DVD.
For #1 - yep, that's the case for everything. Audio is inferior to even DVD.For #2 - I've seen some things that I believe would make an upscaled DVD look good like you suggest, mostly kids stuff. As a whole the quality is typically around upscaled DVD though. There are some HD selections that look better than DVD, but they are very few and far between except for TV series stuff. And even the HD stuff isn't nearly as good as Blu Rays, not only because of gimped audio, but picture quality just isn't nearly as good.
Netflix streaming has its purpose, but anyone thinking this is going to replace Blu-Ray is misguided.
It's just not going to happen.
